Royal Caribbean is known for its wild and fun theme nights, and cruisers certainly dress the part.
From White Night to Formal Night, Tropical Night, 70s Night, and more, you will want to pack accordingly to fit in with the masses.
Some guests love to go all out with costumes and coordinated outfits among party members, while others prefer to keep it simple.
Royal Caribbean's Crown & Anchor Society social media team recently took to its Facebook page to ask cruisers about their theme night packing lists.
"Calling all theme night lovers! What’s the funniest thing you’ve ever packed for a theme night on board? 👀 Tell us in the comments!" the post reads.
Within one day, over a dozen Royal Caribbean cruisers shared their most over-the-top theme night outfits — and you can certainly tell these weren't last-minute packing decisions.

Dress Your Best Night

Although many associate Dress Your Best Night on Royal Caribbean ships with elegant gowns, button-down shirts, and even tuxedos, ErikChristy Bray's travel party took a different approach.
Bray attached a photo of ten cruisers dressed as Mrs. Helen Roper from "Three's Company." One passenger even held a framed photo of Roper's husband, Stanley, in the popular '70s sitcom.

Disco Night is all about sparkles, flashy accessories, and funky shoes.
While Yvonne P. Dumont certainly brought the shimmery clothing, she also went one step further with colorful wigs.
White Night

Normally, White Night is cause for concern since it often aligns with Italian Night in the Main Dining Room (white shirts + red pasta sauce = disaster).
However, Tom Place found a creative way to dress the part while keeping their clothing safe by simply wearing Royal Caribbean-branded robes!
Halloween

Royal Caribbean encourages guests to dress up for Halloween. Just because you're in the middle of the ocean doesn't mean you shouldn't be able to wear a fun costume!
Walter Terry's family went the extra mile, dressing up as Gru, Lucy Wilde, and Minions from the beloved "Despicable Me" franchise.
'60s Night

The '60s were a period of high optimism, revolutionary fashion and music trends, and cultural change. The iconic hippie style is one of the most defining looks of the era.
Nella Gambrell's entire travel party definitely showed up for '60s Night — think wigs, flower crowns, tie-dye shirts, fringe vests, and peace sign accessories.
'70s Night

My mom grew up during the '70s and once told me that she remembered when she got her first pair of bell-bottom jeans. Flared denim, however, wasn't the only popular trend during the decade.
Jennifer Bell and her husband embraced the playfulness of the era with wigs, a fun maxi dress, and wide-collar shirts with colorful patterns.
'80s Night

'80s fashion was bright and bold, which is why it makes such a great cruise ship theme night.
Kathleen Donnelly shared an image of her family's '80s night costumes, complete with neon green lace gloves, tutus, bright pink headbands, and geometric-patterned shirts.
