Princess Cruises Dress Code: Formal Nights, Smart Casual, And What People Actually Wear

Smart Casual is the standard most nights. Princess describes it as clothing similar to what you might wear to a restaurant at home, such as dresses, skirts, trousers, blouses, shirts, or polos.

Princess also notes that shorts and swimwear are not allowed in the restaurant under its smart casual guidance.

Formal Night is dressier, especially in the main dining rooms. Princess’ formal guidance includes options such as evening gowns, cocktail dresses, elegant pant suits, suits, dinner jackets, and slacks.

That is the official version.

The real-life version is usually a little broader.

You will likely see some people dressed beautifully. You may see gowns, suits, ties, cocktail dresses, sparkly tops, dress shoes, and families taking formal photos.

You will also likely see people dressed much more casually.

That is where expectations matter.

Princess may still lean more traditional than some lines, but that does not mean every passenger is walking around like they are headed to a black-tie wedding.

For women, that might mean:

• A casual dress
• A blouse and pants
• A skirt and top
• Nice jeans with a polished shirt or sweater
• A jumpsuit or pantsuit
• Comfortable shoes that still look dinner-appropriate

For men, that might mean:

• Khakis or dress pants
• Nice jeans
• A polo shirt
• A button-down shirt
• A sweater or casual jacket
• Clean shoes or nicer sneakers

This is not meant to be intimidating.

Think less “formal event” and more going out to a decent restaurant without looking like you just came from the pool.

That is probably the easiest way to pack.

This is when people who enjoy dressing up really have a reason to do it.

You may see photographers set up around the ship, couples taking pictures, families dressed up together, and people treating the evening as a special occasion.

For some cruisers, that is one of the best parts of Princess.

For others, it is simply dinner.

The important thing is this:

You do not need to dress like you are attending a gala unless you want to.

A cocktail dress, dress pants and a blouse, a nice jumpsuit, a button-down shirt with slacks, or a blazer can all fit the feel of the evening without requiring a full formal wardrobe.

Some passengers will dress up more than that. Some will dress up less.

For most people, the practical target is dressier than usual, not necessarily truly formal.

That distinction matters.

If packing a suit creates stress, luggage issues, or extra expense, you can likely dress nicely without going that far.

For many men, a good middle ground would be:

• Dress pants or nice chinos
• A button-down shirt
• An optional blazer
• Dress shoes or clean, nicer shoes

A tie can be added if you enjoy wearing one, but many people will not.

For women, the equivalent might be:

• A cocktail dress
• A maxi dress
• Nice pants and a blouse
• A dressy jumpsuit
• An elegant sweater or wrap
• Comfortable shoes that work with dinner attire

The goal is to look put together.

Not necessarily overdressed.

Princess’ smart casual guidance focuses on restaurant-style clothing, but real-life enforcement can vary by ship, venue, itinerary, staff, and the specific outfit.

If you want the safest packing strategy, bring at least one or two pairs of pants that are not jeans.

That gives you flexibility for dining rooms, specialty restaurants, formal nights, and any venue that feels a little dressier.

But if your style is clean, simple, and put together, jeans may not be a major issue on many sailings.

The better question is not “Can I get away with it?”

The better question is:

Will I feel comfortable walking into the dining room dressed this way if other people are more dressed up?

That is the standard we would use.

For dinner in the main dining room or specialty restaurants, we would avoid:

• Swimwear
• Pool coverups
• Flip-flops
• Baseball caps
• Sleeveless undershirts
• Very worn-out shorts
• Beach clothes
• Anything that looks like you just came straight from a lounger

Princess’ published guidance specifically says shorts and swimwear are not allowed in the restaurant under its smart casual guidance.

That does not mean every ship will handle every situation the same way, but it is a good baseline.

If you would feel awkward wearing it to a sit-down restaurant at home, it is probably not the best choice for a Princess dining room.

If you do not want to dress up on formal night, you usually have other options.

You can keep things more casual by eating at the buffet, grabbing casual food, ordering room service where available, or spending the evening in areas where the dress code feels less formal.

That is one of the reasons we do not think anyone should panic about Princess formal nights.

You have choices.

You can dress up and enjoy it.

Or you can keep things simple and still have dinner.

As a general rule, shorter cruises may have one formal night, while longer cruises may have two or more.

The exact schedule can vary, so the best strategy is to check your Princess app, onboard schedule, or dining information once you are closer to sailing.

For packing purposes, most people should be fine with one flexible dressier outfit for a shorter sailing and two dressier options for a longer cruise.

You do not need a different formal outfit for every dressier evening unless you want one.

A Princess Alaska cruise may feel different from a Caribbean cruise.

A Mediterranean cruise may feel different from a short West Coast sailing.

A longer cruise with more retired travelers may feel different from a short vacation sailing with more families.

That does not mean the rules completely change.

But the vibe can.

For Alaska, people often care more about layers, comfort, weather, and practical clothing.

For Europe, people may naturally dress a little more polished for evenings.

For the Caribbean or Mexico, daytime clothing may be much more casual, but dinner still usually calls for something cleaner and more put together.

This is why we would not pack based only on the words “formal night.”

Pack based on:

• Your itinerary
• Your dining plans
• Your comfort level
• Your luggage situation
• Whether you actually enjoy dressing up

That is a much better approach.

For daytime, we would pack normal cruise clothes:

• Shorts
• T-shirts
• Comfortable walking shoes
• Swimwear
• Layers depending on the destination
• A light jacket or sweater for cooler indoor spaces

For dinner, we would pack a few flexible pieces:

• Nice pants or dark jeans
• Polos or button-down shirts
• Casual dresses or nicer tops
• Comfortable dinner shoes
• A sweater, wrap, or light jacket

For formal night, we would pack one outfit that can dress up without taking over the suitcase.

That might mean a dress, jumpsuit, pantsuit, blazer, button-down shirt, or dressier pants.

The key is rewearing pieces.

You do not need a separate outfit for every photo, dinner, and evening.

Unless that is part of the fun for you.

You will likely find other people doing the same. Formal photos, nicer dinners, and dressed-up evenings still fit the Princess brand.

But if you do not enjoy dressing up, you do not need to let formal night scare you away from Princess.

There is a middle ground.

You can look nice without packing formalwear.

You can skip the main dining room that night if you want to stay casual.

You can choose clothes that are comfortable, wrinkle-resistant, and easy to reuse.

The goal is not to impress strangers.

The goal is to enjoy your cruise without feeling out of place.

Our advice would be:

Pack one level nicer than your most casual cruise clothes.

That means comfortable daytime outfits, smart casual dinner clothes, and one or two dressier options depending on the length of the cruise.

For most people, that is enough.

You will be prepared for the dining room.

You will be comfortable around the ship.

You will not overpack.

And if formal night turns out to be more relaxed than expected, you will still look good without feeling like you hauled half your closet onboard for no reason.
