Between daytime excursions, lazy afternoons by the pool and semi-formal dinners, cruises require a few wardrobe changes throughout the day. This variety of activities poses problems for travelers trying to streamline their packing list. If packing for a summer cruise stumps you, take inspiration from these simple vacation-ready outfits.

A matching shorts and top set makes for an easy outfit that's breathable and so cute. It's perfect for a day filled with tourism fun.

Hawaiian shirts are totally acceptable on cruise ships or any other kind of tropical vacation. Give it a fashionable twist by rolling up the sleeves and tucking it into an equally-as-bright skirt.

Linen pants or shorts and a relaxed button-down are must-haves for guys. These pieces are lightweight enough to wear during the day, yet nice enough to dress up at night.

And, ladies, definitely bring along some white linen pieces, as well. This sleeveless jumpsuit is comfortable enough to wear while trekking around a port city and chic enough to wear for evening with tons of jewelry and espadrilles.

Men should bring along at least one (lightweight) blazer to wear for nice dinners on the boat or for chilly days spent roaming a nearby city.

A simple striped tunic serves as swimsuit cover-up or easy, lightweight dress for warm, casual days. Multi-purpose items save serious suitcase space when packing light!

A relaxed shirt and short set looks polished and put-together with little effort. A straw Panama hat is a must, for men and women.

Linen pants and an oversized button-down are extremely versatile and each can be dressed up or down. Block-heel sandals are both practical and stylish.

Not into Hawaiian shirts? A blazer in a bright tropical print works, too! White pants and a T-shirt keep the look casual.

Leave heels at home. Flat, strappy sandals work with everything from dresses to shorts to cropped pants.

Sleek sneakers (and, duh, Hawaiian shirts) are always a good idea. Ditch trouser socks for no-show ones and wear sneakers with slacks or shorts.

Be sure to pack at least one pair of jeans for unexpected chilly temps. Flowy, bright blouses and messy up-dos give an effortless look to shorts or cropped pants.

The Takeaway: Don't overthink your outfits too much. Keep it simple, colorful and comfy. Happy cruising!
