What Is the Dress Code Like on an Ultra-Luxury Cruise in 2025?

If you’ve booked an ultra-luxury cruise for 2025, or you’re seriously thinking about it, first of all: good choice. There’s simply nothing better than sailing from place to place in complete luxury, with everything included. And that’s not hyperbole, there’s nothing better. 

But if it’s your first ultra-luxury cruise, you might have certain preconceptions about how people dress, and if you do, you’re not alone. The dress code on luxury cruises has evolved, and these days it’s far more chic than stuffy.

Let’s break down what you need to know, from daywear to dinner attire, and what’s completely optional (but fun to bring).

First Things First: No, You Don’t Need a Tuxedo

Let’s clear up one of the biggest myths right away: ultra-luxury doesn’t mean overly formal. We’ve moved on from the gaudy formal nights of the nineties and noughties. We can look smart while also feeling comfortable. 

Don’t get me wrong, you’ll still find elegance (lots of it), but most ultra-luxury cruise lines in 2025 have left behind the rigid dress codes of the past. In fact, many have adopted a “smart casual by day, elegant by night” approach that keeps things polished but comfortable.

Daytime Dress Code: Comfortable, Cool, and Considered

During the day, think resort casual. You’ll want clothes that are comfortable, breathable, and appropriate for the destination.

For women:

• Linen trousers, relaxed blouses, sundresses, or tailored shorts

• Comfortable sandals, sneakers, or espadrilles

• A swimsuit or two for the pool/spa, plus a chic cover-up
   

For men:

• Polo shirts, short-sleeved button-downs, or light T-shirts

• Chino shorts or lightweight trousers

• Casual loafers or trainers
   

If you're heading out on an expedition cruise (like to Antarctica or the Galápagos), daywear will obviously be more active. Bring waterproof layers, base gear, and sturdy footwear. Many expedition cruise lines will provide boots and parkas for rental, so you don’t need to lug them across the world.

Evening Dress Code: Elegant, Not Over-the-Top

Look, if you want to dress up, you should absolutely dress up. Even those who hate wearing suits are required to make a bit more of an effort in the evening. You’re dining in stunning restaurants with Michelin-standard cuisine, so dress how you would in a top London restaurant. You want to look nice, but it’s not black-tie unless it specifically says so.

Common terms you’ll see (they all mean the same thing):

• Elegant Casual / Country Club Casual – the most common evening dress code

• Formal Optional / Gala Night – usually once per cruise, if at all

• Resort Chic – stylish, upscale, and relaxed

For women:

• Midi dresses, flowing jumpsuits, silk trousers with a blouse

• Flat sandals or wedges are perfectly fine — heels optional

• Statement jewellery or a nice wrap can elevate the look without overpacking

For men:

• Long trousers (no shorts), collared shirt (button-up or polo)

• Blazers are optional unless you’re into them

• Closed-toe shoes (loafers or dress sneakers both work)
   

If you’re cruising with Silversea, Seabourn, Regent Seven Seas, Scenic Eclipse, Explora Journeys, or Ponant, this kind of relaxed elegance is the norm. Some might offer an optional “formal night,” but there’s zero pressure to participate. You’ll look perfectly at home in a tailored jacket or a stylish maxi dress.

What Not to Wear (at Least After 6 PM)

Even on the most laid-back ships, some things are better left for daytime lounging. Most ultra-luxury cruise lines ask that you avoid the following in restaurants and lounges in the evenings:

• Beachwear or swimwear

• Tank tops or gym clothes

• Baseball caps or visors

• Flip-flops or overly casual sandals
   

It’s not about being snobby, it’s just about keeping a certain level of ambiance when everyone’s enjoying a fine meal or a jazz trio over cocktails.

A Note on Destination-Specific Dressing

Your itinerary matters a great deal. What you pack for a luxury Mekong cruise will be different from a sailing around Iceland.

• Tropical cruises: Lightweight fabrics, sun protection, and waterproof sandals

• Polar or expedition cruises: Thermal layers, waterproof outerwear, and performance clothing

• Cultural regions (like the Middle East or parts of Asia): Modesty is key for shore excursions–  long sleeves, shawls, and trousers are recommended
   

Do You Need to Dress Up at All?

When you’re spending ‘ultra-luxury’ money, you’re entitled to dress how you like, but part of the joy of ultra-luxury cruising is the experience, and that includes dressing up a little if you feel like it. 

There’s something special about enjoying a beautiful meal, with gorgeous sea views, in clothes that make you feel confident. But no one is expecting red carpet looks.

In fact, one of the best things about modern ultra-luxury cruising is the freedom it offers: freedom to be comfortable, stylish, and, most importantly, yourself.

One last tip

The best advice? Pack like you’re going to a very nice resort — and then edit down. Choose versatile pieces that mix and match, and don’t forget a light jacket or wrap for breezy evenings.

So, what’s the dress code like on an ultra-luxury cruise in 2025? It’s exactly what it should be: polished without being pretentious, stylish without being stiff. A balance of comfort, confidence, and quiet glamour.

And if you’re still unsure? When in doubt, bring the linen. It never lets you down at sea.
