Comfy poofy LBD

The top fit a little big. I'm a 34D and still found the top could have been more snug. If you're between sizes, I would size down!

A classic black formal dress

Beautiful dress and it has pockets!!!! Fabric is stunning and it has side zipper for top of dress that makes it a secure fit and easy to put on and take off over the head. Elegant and classy. Perfect for formal event. Perfect dress for the summer black tie wedding I attended in NYC!

Five stars isn’t enough

Obsessed. This dress is simply amazing! The bodice is stretchy and super comfortable, while the skirt brings the drama in the best way. It’s definitely a statement piece, but it didn’t feel like it was wearing me. You could easily wear this to a formal event.

Fun Cocktail Dress

This dress hit just the right note for an opening at The Met. Fits TTS with enough support in the bodice that I did not need to wear a bra, which is a rarity for me. The bodice material is more stretchy than structured, so I added a belt to delineate my waist. On my 5’4” frame, the hem hit me a little above my ankles so that my shoes were fully visible. The bubble-hem skirt has a lot of flounce, making this a super fun dress to wear; I didn’t want to take it off when I got home! It’s easy and comfortable to wear and even has a pocket on the left side. Materials felt substantial and of high quality. This is a great dress for a middle-road formal event that can be pushed more or less formal with the right accessories.

Comfortable and flattering!

I would have ordered a S but it wasn’t available so I gave the XS a try. It worked (S would have r worked too)! Got many compliments and it was so comfortable! Perfect for a spring formal wedding at a vineyard!

Perfect for a black tie optional wedding

Wore it to my best friends black tie optional wedding, was not a bridesmaid but she requested I wear black. Im short so renting can be hard with the length so midi usually fits as full length for me so this was perfect! I was nervous the material on the top made it too casual but it was fine, just wore nipple covers and first time I haven’t felt the need to wear spanx to a wedding in a while which was a added bonus! Would definitely recommend to any short girls

Such a fun dress!

I wore this dress to a work awards banquet and it was perfect - I felt beautiful but still work appropriate. I ordered a medium with a small as a backup and both fit but I ended up wearing the small - the top is thick but stretchy and I felt like the tighter top didn’t bunch up as much. I wore a strapless bra under it just for more support although I could have gotten away without one. The balloon hem was really fun and different, and the pockets meant I didn’t need to carry a purse. Rent this dress, you won’t regret it!

Comfiest fancy dress ever!

I wore this dress to my work’s holiday party - I feel like it could be dressed up to be black tie or kept more low key as I wore it. It was super comfortable and flattering and got TONS of compliments. Great reliable option.

Stunning & classy!

I wore this to a friends wedding and it fit like a glove! The fitted top part is made of a quite thick material and has a little stretch, but not much so keep that in mind. I felt like I was having a Carrie Bradshaw moment in this dress PLUS it was flattering so I could eat in peace without fear of bloating, like one would in a body con dress.

Simple, classic, with a surprise bubble skirt

I loved this dress. So comfortable and flattering. Basic black with a twist. The material did not wrinkle and I loved the tea length. Hosted a party in my home in it and was easy to wear and move in.

Chic and Easy

This fit true to size, and super comfy to wear all night and dance in. Easy to wear and an instant chic moment. The skirt was longer than I expected, and the bodice not as elongating on my 5'8 frame. Would still highly recommend!

So cute

This dress was so fun, I loved the bubble hem. However, it was tight through the chest. If the bodice didn't have a lot of stretch I wouldn't have been able to wear it. Fit in the waist and skirt was fine. The neckline was also a bit weird, the shape of the one shoulder didn't sit quite right and was fussy.

Gorgeous event dress!

I loved this dress, I had sized down based on other reviews, and was able to make it work but you need to make sure you are renting based on chest size. It has pockets which I loved! It is made of thick, but comfortable material, and does not need any readjusting. Would definitely rent again.

Fit was just a little large in the hip area and at the shoulder. Otherwise, gorgeous dress that garnered lots of compliments and the pockets were an added bonus.
