Cruise Formal Night: What to Wear – UK Guide 2026

Formal nights cause more packing worry than almost anything else, particularly for first-time cruisers. The good news is that you rarely need a suitcase full of gowns or a hired tuxedo. Work out how formal your cruise line is, decide whether you want to join in, and then pack a few pieces that work hard.

What does “formal night” mean on a cruise?

A formal night is an evening when the cruise line asks guests to dress up for dinner and, usually, in the main bars, lounges and theatre too. It’s often the night of the captain’s welcome drinks, a special menu and the professional photographers, which is why many people enjoy it. The dress code typically starts in the early evening (P&O Cruises, for example, applies its evening dress codes from 6pm) and runs until late.

Every line uses its own name and sets its own standard. “Black tie” or “gala” on a traditional British line really does mean dinner jackets and evening gowns, while an “elegant” or “chic” night on a more relaxed line may just mean a smart dress or a blazer. Your cruise documents, the line’s app or the daily programme left in your cabin will tell you which nights are formal.

Cruise formal night dress codes by cruise line

These are the lines UK cruisers ask about most. The summaries come from each line’s own dress-code guidance at the time of writing. Policies change, so always check the current version before you pack.

A few details worth knowing:

• P&O Cruises is one of the more formal lines, and its UK passengers tend to dress up. Its dress-code guidance says a 14-night cruise typically has four Black Tie nights, and the evening dress code applies to guests aged 18 and over. Don’t plan on wearing jeans on a Black Tie night, except in venues the ship marks as casual that evening.
• Cunard is the most traditional of the six. Even its non-gala evenings expect smart clothes, and many guests wear full black tie on Gala Evenings, especially on Queen Mary 2’s transatlantic crossings. See Cunard’s what to pack guide.
• Princess Cruises says shorter cruises typically have one formal night and longer voyages two or more. It also keeps the buffet and casual dining open every evening with a relaxed dress code (Princess packing tips).
• Royal Caribbean lists one Dress Your Best night on a 5-night cruise, two on 6 to 10 nights and three on 11 to 14 nights (Royal Caribbean dress code FAQ). The ship can vary this.
• Celebrity Cruises says itineraries feature one or two Evening Chic nights, and that smart casual is acceptable if you don’t want to take part (Celebrity dress code).
• MSC Cruises is the most relaxed of these lines about what you wear, but it still asks guests not to wear shorts, flip-flops, vests or T-shirts in its restaurants on Gala Night (MSC – what to wear).

If your line isn’t listed, search for “[cruise line] dress code” on its official website rather than relying on forums, where advice is often years out of date.

What women can wear on a cruise formal night

There’s no single correct look. Anything you’d wear to a wedding reception, a black-tie dinner or a smart Christmas party will fit in on almost any ship.

• Dresses: a cocktail dress, midi dress or maxi dress is the most popular choice. Floor-length gowns are common on Cunard and P&O but are never required. Jersey, crepe and other fabrics with some stretch pack and wear best.
• Jumpsuits: a smart, plain or embellished jumpsuit is just as acceptable as a dress, and easier to pack.
• Trousers: wide-leg or palazzo trousers with a sequinned or silky top, or a dressy trouser suit, are explicitly welcomed by P&O, Princess and others.
• Layers: restaurants and theatres are air-conditioned, and open decks can be breezy after dark, even in the Mediterranean. A pashmina or wrap (opens in a new tab) (paid link), a bolero or a fitted jacket keeps you warm without hiding the outfit.
• Bag: a small evening clutch (opens in a new tab) (paid link) or crossbody bag that holds your cruise card, phone and lipstick is all you need – you’re never far from your cabin.

What men can wear on a cruise formal night

Men have fewer choices but more freedom than many expect.

• Dinner suit (tuxedo): the classic choice on P&O and Cunard. Black or midnight navy with a white dress shirt and a black bow tie. A white or ivory tuxedo jacket is a nice option on Caribbean and summer Mediterranean cruises. If you don’t own a bow tie, a pre-tied bow tie (opens in a new tab) (paid link) is easy and nobody can tell.
• Dark lounge suit and tie: accepted as formal wear by every line in the table above. Navy, charcoal or black works best, and the jacket and trousers can be worn separately on smart-casual evenings.
• Blazer and smart trousers: enough for Celebrity’s Evening Chic and MSC’s Gala Night, and many men wear the same on Royal Caribbean. On P&O or Cunard, add a tie at least.
• Shirts: a double-cuff shirt looks smarter but needs cufflinks (opens in a new tab) (paid link). Pack one more shirt than you think you need – shirts are the item most likely to get marked at dinner.
• National dress: a kilt or other formal national dress is generally welcomed on formal nights.

Shoes and accessories

Ships move, stairs are everywhere and you may be on your feet for drinks, dinner and a show. Choose comfort first.

• Women: block heels, low heels, smart wedges or embellished flats are easier than stilettos on a moving ship and on long corridors. If you love heels, bring a pair of foldable flats for the walk back to the cabin.
• Men: black Oxford or Derby shoes, polished or patent. Dark socks. Brown shoes and trainers look out of place on the stricter lines.
• Jewellery: a travel jewellery organiser (opens in a new tab) (paid link) stops chains tangling and keeps earrings together, which matters in a small cabin. Leave valuable pieces at home or use the cabin safe.
• Restyling: a different necklace, earrings, scarf, tie or pocket square changes an outfit more than you’d think, so accessories are the easiest way to cover several formal nights.

What counts as too casual?

On a formal night, these are usually not acceptable in the main restaurants or the venues where the dress code applies:

• Shorts, swimwear and beach cover-ups
• Flip-flops, sliders and bare feet
• Sportswear, gym kit and caps
• Vests and T-shirts
• Ripped or distressed jeans

Smart jeans are a grey area. Celebrity explicitly allows designer jeans on Evening Chic nights, and MSC is relaxed. But P&O Cruises doesn’t allow denim on Black Tie nights in the formal venues, and Cunard’s evening dress code is strict, so leave jeans for the daytime on those lines.

Do you have to dress formally on a cruise?

On most lines, no – formal night is optional for you, but the dress code applies in certain places. If you want to eat in the main dining room or sit in the main bars on a formal night, you’re expected to follow the code. If you don’t want to dress up, you simply eat and spend the evening somewhere the code doesn’t apply.

That’s why it’s worth reading your line’s policy before you decide what to pack. On a relaxed line, a smart dress or blazer gets you everywhere. On P&O Cruises or Cunard, skipping formal attire means skipping some venues for the evening.

What happens if you don’t want to dress up?

Nobody will make you change, but you may be politely redirected if you try to enter a formal venue in casual clothes. In practice, most people who skip formal night:

• Eat at the buffet, which on most ships keeps a relaxed dress code in the evening.
• Use a casual venue, such as a pool-deck grill, pizza counter or pub-style bar, where available.
• Order room service and have a quiet night in.
• Book a speciality restaurant, although some apply the evening’s dress code too, so check when you book.

Which venues stay casual varies by ship and sometimes by evening. The daily programme lists the dress code for each venue, so check it when you get on board.

How many formal outfits should you pack?

You don’t need a different outfit for every formal night. Re-wearing the same suit or dress is completely normal on a cruise, and changing the accessories is enough. This is a sensible starting point:

Men can usually get away with one dinner suit or dark suit for the whole cruise, with a spare shirt and a second tie or bow tie. Women often take two outfits and change jewellery, shoes or a wrap for the other nights.

Remember that most evenings are smart casual, not formal, so your other evening clothes matter just as much. Our complete cruise packing list covers how many outfits to bring overall.

Packing formal wear without creases

Irons and garment steamers are banned on many cruise ships, so plan ahead rather than relying on fixing creases on board.

• Choose forgiving fabrics. Jersey, crepe, sequins and many synthetic blends crease far less than linen, silk or pure cotton.
• Use a garment bag (opens in a new tab) (paid link) for a suit or structured dress. Fold it once, lay it on top of your case and unpack it first.
• Roll, don’t fold, soft dresses and jersey, and pack shirts buttoned up with tissue paper between the folds.
• Hang everything as soon as you reach the cabin. Hanging clothes in the bathroom while you shower releases light creases.
• A pump-spray wrinkle release spray (opens in a new tab) (paid link) helps on stubborn creases. If you’re flying with it in your hand luggage, keep to the 100ml liquids limit.
• Use the ship’s pressing or laundry service for anything that really needs it. It gets busy on formal-night days, so send items early.

Cabin storage and embarkation day

Cabin wardrobes are small, and hanging space runs out quickly when two people bring evening wear.

• Hang the long items first. Dresses and suits take priority. Folded clothes can go in drawers or packing cubes under the bed.
• Bring a few slim hangers if you’re packing several outfits – ships provide some, but rarely enough for formal wear.
• Keep shoes in bags so they don’t mark your clothes and can be stored under the bed.
• Don’t pack your formal outfit in your hand luggage. On most lines the first evening is casual, and your suitcase may not reach the cabin until later in the day. Keep a smart-casual change in your embarkation bag instead.

Our cruise cabin essentials guide has more ideas for making the most of a small cabin.

Formal wear when you’re flying to the ship

On a fly-cruise to the Caribbean, the Mediterranean or further afield, the airline’s baggage limit, not the cruise line, decides how much you can take. Formal wear is often what pushes a case over the limit.

• Build around one colour. Black, navy or another dark colour means one pair of shoes and one bag go with everything.
• Wear or carry the bulkiest items. Wear your suit jacket on the plane, or carry it in a garment bag if your airline allows it as part of your cabin baggage.
• Choose a jersey dress or jumpsuit that rolls small instead of a structured gown.
• Weigh your case before you leave and again before you fly home, when souvenirs add weight.
• Check whether your line has formal nights at all on that sailing – many Caribbean and short cruises have fewer than a UK round-trip cruise.

For warm-weather cruises, see our Mediterranean cruise packing list and Caribbean cruise packing guide. If you’re heading north, the Norwegian Fjords packing list explains why a warm wrap or jacket is worth packing for evenings on deck.

Where to buy cruise formal-night outfits in the UK

You don’t need a specialist “cruise wear” shop. Formal-night outfits are the same clothes you’d buy for a wedding, a black-tie event or a Christmas party.

• High-street and department stores: Marks & Spencer, Next, John Lewis and Monsoon all sell occasionwear and men’s suits online and in store, and returns are straightforward if something doesn’t fit.
• Partywear specialists: stores such as Phase Eight and Coast focus on dresses and jumpsuits for special occasions.
• Menswear and suit hire: suit shops such as Moss sell and hire dinner suits. If you hire, check that the hire period covers your whole cruise, plus travel days.
• Online fashion retailers: ASOS and similar sites have wide ranges and fast delivery, but order early so you have time to return what doesn’t work.
• Preloved: Vinted, eBay and charity shops are good places to find a dinner suit or evening dress you’ll only wear a few times a year.
• Amazon UK: handy for accessories you might otherwise forget, such as cufflinks, a bow tie, an evening bag or a garment bag. We’ve linked a few on this page.

Order at least three or four weeks before you sail. That leaves time for a second size, a return or a simple alteration such as taking up trousers. Try everything on with the shoes you plan to wear, and sit down in it – you’ll spend most of formal night at a dinner table.

Formal wear for children

Many families like to dress children up for the photos, but it’s rarely compulsory. On P&O Cruises’ family-friendly ships, for example, dress codes don’t apply to under-18s. A smart outfit, such as a shirt and chinos or a party dress, is usually plenty.

Formal night packing checklist

• Formal outfit(s) that meet your line’s dress code
• Smart-casual outfits for the other evenings
• Evening shoes you can stand and walk in, plus flats if you wear heels
• Tie or bow tie, cufflinks and a spare shirt
• Evening bag and jewellery
• Wrap, shawl or light jacket for cool decks and air-conditioning
• Garment bag or tissue paper for packing
• A few slim hangers and shoe bags

Tell the packing planner whether your cruise has formal nights and it adds the right evening items to your personalised list – or a versatile option if you’re not sure yet.
