Great party shirt, but size up for larger rib cage

I originally rented this in a 4 and couldn't button the back around my rib cage. Sized up to a 6 and loved it. Fabric is a bit stiff, but the open back and bow makes the shirt. Would rent again.

Obsessed. May buy.

This looks killer. I normally don’t wear backless anything because I think that I can’t pull it off, but this is so flattering. I did need help with the buttons and the tie. Love the navy color and nice fabric.

Lots of compliments

Loved this top! Fits perfect! I wore a small. You need a hand to put it on and get off but otherwise it’s great! it’s high quality. Pairs well with a high waisted pant or skirt.

Unique.

I think this shirt runs slightly small, but overall I loved it. The navy color makes it seem a bit on the conservative side then bam--open back! I would rent again.

Fun summer top

This was out of my comfort zone, but I was super happy I took a chance on it. I wore it with high waisted jeans, so stomach only showed a bit. Back is open, so you can't wear a regular bra with it, but fabric is substantial enough to provide coverage in front. Wore it for lunch and bar crawl along river walk on a perfect early summer day.

Cropped and trendy

I rented this to wear with a high waisted skirt, but it was way more fun with jeans and heels :) The back is open, so I didn't wear a bra and it was fine. Super cute!

Perfect holiday non-dress option

Loved the shirt, got lots of compliments and the fit was great! 4 stars not 5 only because I thought it was black from the website pictures but it’s actually dark navy!

Cute date night option

Not necessarily my favorite rental ever, but a cute date night option for a summer night. True to size. Can’t wear a traditional bra. Despite it looking like the bottom was tight, it didn’t feel tight at all. Light material and I love the navy with black velvet ribbon combo.

My favorite piece... honestly with bigger boob's, i expected to potentially have issues but it was perfect with the right skirt. I didn't even need bandaids :) but it was very flattering and worked very well with the higher waisted skirt I had.

Flattering - purchased!

Ordered this thinking it would be good for a nice dinner out on vacation this summer, but the fabric is more of a cool weather weight. It looked so nice on and the price was so good I purchased it to wear this fall. Fwiw, couldn't find a bra to wear with it that didn't show...might be able to wear without a bra, but more likely will use boob tape for a little lift.

Great with jeans

My husband loved this top! Wanted me to buy it. As others have said there’s no give and it’s short. But it’s fun and flirty and the color and material are great.

So cute!

I loved this top and wore it to a bachelorette/bachelor party. Our theme was white pants and navy blue tops for the ladies. I felt so good in it and am considering buying it. The open back is a nice surprise, and I didn’t have to wear a bra.

gorgeous details

Everything about this top is lovely. The color, the velvet ribbon closure at the neck, the waistband with three tiny buttons, the perfectly puffed sleeves. I’m not comfortable going Brolass, so was grateful that I have a backless bra that worked with this top. Will definitely rent again and might buy.

This was out of my comfort zone with the puffy sleeves but so glad I went for it! The back is flirty but with the full coverage in front, it still feels put together

Beautiful and feminine

I love a conservative top! Beautiful material, but no give. Fit snug, but I was ok with that and just didn't wear a bra and it was perfect and very flattering. Conservative but feminine with open, tie back. Would rent again.
