Summer Date Night

Perfect romper for summer date night or party. Paired it with wedges for height. The fabric is slightly thin, but couldn't see nude undergarments. Shorts are a little short, but the wedges helped. Wore it twice and would rent again.

Loved this romper!

Super cute, didn't have to wear a bra with it because of the material and the overhang. Was perfect for my height likely because it was strapless. Would absolutely rent again!

I rented this for a cruise and it was more casual than I expected. It would be very cute for walking around/daytime vacation seeing because it is so comfortable!

I love this outfit. The colors and stripes are so fun. Has a linen type feel to it. Only flaw is the lack of pockets.

Color is fabulous

I would 100% rent this again. I wore it on vacation in key west. It was lightweight, fit well. I didn't wear a bra and it was fine. The color is beautiful. Lots of compliments on this.

Size 10-12 romper that fits?! It's a miracle

I've basically come to terms with the fact that rompers and shorts are never going to be flattering on me but this cute little number changed my mind! I wore it on a hot night - it was so breathable and comfortable. Might have to rent again before summer is over.

Cute romper, loved the colors. I have an athletic build and a long waist so this didn't do anything special for me, but still happy to wear once.

This romper was cute and comfortable. I have a long torso and I found it was a good length--it covered my butt and didn't ride up.

Fun and easy to wear - boardwalk outfit

I wore this romper on a day with my family at the boardwalk. It’s very casual and really cute. Very light weight but not revealing, and more fun than sexy. Only complaint that if the waist was even a tad smaller I couldn’t have gotten it over my butt - and my butt is medium to flat - any more muscles and I wouldn’t have been able to put it on. I do think a small (versus XS) probably could’ve worked just the same though.

This is the easiest, cute/sexy “throw-on”!

I wore this multiple times because it is so easy and in NC, and on vacation, it was HOT OUT. So easy to slip on, didn’t need a bra because the flap covers everything, airy and adorable with chunk heels or flat sandals. I highly recommend. You will wear it more than you think!

I loved this and wanted to purchase. So comfy, cute and no need for a bra. Win all around for me. Length was perfect and not too short. I could see how it would be too short on a taller person.

Loved this outfit!

I was hesitant to rent this at first, as the color in pictures looked a little too neon but it was perfect in person! I could wear it around the resort without a bra & it looked great as a cover up or out to dinner at night. Would rent again.

I don't usually wear rompers as i'm 5'11 so they're not very flattering on me but this fit so perfect! Great for taller girls and the layered look style of it is also very flattering, got so many compliments. So cute for summer.

Perfect Romper

This romper is perfect- flows nicely and no need for a bra. Dressed this up for a date and dressed down for a family summer picnic.
