Petite-friendly

This was a comfortable and classy dress. Length was petite friendly but arm hole was slightly tight. Wrinkled easily.

Head turner

This is a gorgeous gown that fits true to size and hits at the ankle for petites. I am 5'4 and it was the perfect length on me. I loved the feel of the fabric and the elastic band around the midsection made for a very flattering cut-out.

Elegant everyday

Wore this on a vacation to Mexico and got lots of compliments. It was elegant without feeling too formal for daytime. The elastic around the waist at the cutout was a bit tight on me.

Simple but elegant!

Wore this for a black tie wedding at a hacienda in Mexico. The material was luxe and skirt heavier than you would think but that's what made it feel and look high quality. I styled it with an Indian scarf and feathers, peacock feather earrings and a RTR teal, small purse. The elastic waist band was comfy but it sits pretty high up especially if you have a short torso like me.

This was super flowy and soft! Wore it to a summer wedding on a hot day and the side cut and flowy material definitely made me cooler!

Fun dress

I really enjoyed this, although I was only able to wear it once out to dinner. The asymmetrical cut and cut-out make it interesting, and sexy, without really being too revealing. Nice material, and doesn’t wrinkle as much as you’d think!

Just modest enough!

I wore this to our work holiday party. Loved the fit. I’m a 0/2 and wore the XS. The small fit but was a little too loose up top for me. XS was perfect. I loved this so much I want to buy it. I felt very comfortable all night. Even received a few compliments!

Simple with a little bit of SPICE

When I tell you I received more compliments on this dress than expected..... This was option B of two dresses I brought to a wedding. I didn't think much of it as it was just a black dress, but I received so many compliments on it. I did not listen to the reviews and ordered my true size and I am glad I did because it stayed in place the whole night. If when you sit you feel its squeezing areas you don't want it to , you can always pull it up and not let skin show. That is what I did when sitting down for dinner. Its all personal preference though. I would for sure rent this dress again.

Great to dress up or down

Loved this dress! I rented for my boyfriend and my anniversary and it was perfect. I paired it with boots to dress it down a bit and it was great but you could definitely make it dressy with heels. I did size up because of the bust- it was cutting it close with the bust being almost too small but sizing it up helped. Would definitely rent again!

Meh

It was a tad large on me. I thought it was going to be more flattering than it was. Not a bad dress by any means and It was very comfortable. It just didn’t photograph well and I had to adjust it a lot.

Wore this to an engagement party and loved the fit. The cut out can be bigger or smaller (needs to have a little shown or does look weird). Got tons of compliments.

MUST RENT

This was the perfect little black dress. I would buy if I could afford. Seriously a must rent. So comfortable and steams nicely so make sure to have a steamer or iron handy. The fabric is lux and soft. The skirt is perfect midi length on me. Sexy little cut out. You need this dress

Nicer than expected!

I rented this thinking it would be a cute summer option. The fabric is slinky & dressier than I thought! I ended up wearing to a concert but also wore with sandals for a casual day look. Elastic didn’t feel too tight anywhere & length was fine.

Perfect for girls night out in the city. Cutout was just enough and I didn’t feel too exposed. Stayed in place and very comfortable through dinner and walking around the city. Elegant and a little sexy at the same time.

Loved It!

I ordered this in a XS and S because it seemed like a lot of reviewers said it ran small, but I am very glad I got the XS because that fit me just fine. I wore this dress to a dinner and drinks event for work in NYC and it was a perfect combo of fun and modern but still relatively work appropriate for a night out. I got a ton of compliments and felt very confident all night long!

Show stopper in silk

This dress was so glamorous and perfect for a night out in Barcelona. The fabric is so silky and substantial, the wrinkles fell out of it after I hung it up after a couple hours. It twirled and photographed well - the top part was a little big on me but not noticeable. The cutouts were classy and flattering as well.

Perfect dress for night out

This dress was so fun and comfortable for drinks on the patio as well as dancing in the club for my hubs' convention in Vegas. Fabric has a sheen to it that elevates it beyond a picnic frock and the cut-outs are very trendy.

Lots of compliments, super flattering

Wore this to a black tie nonprofit fundraiser. The dress is very comfortable. I could move around easily, and the elastic bands in the skirt and top kept everything in place. You can wear a strapless bra with this as well. I ordered a medium and large (just in case) because I’m always nervous about things being too tight on my hips, but the medium was perfect. Loved the small cutout- it was modest but also added some fun to the dress. I definitely would rent this again.

Perfect, easy black dress to dress up or down

I wore this to a young professional event/ party. It was modest enough, but still fun with the one shoulder and small side cut out. I would definitely rent again in the summer to wear with flat sandals out to dinner or during the day on a vacation. Easy yes!

A lot of compliments, but small in chest area. I felt like I could have did a large to accommodate my chest, and the side opening that was never stayed opened. It ended up being an one piece the whole time.

Classic and chic

Really classy dress but also simple had woman stopping to tell me how lovely I looked. Dressed it up add accessories it was a really stunning piece. I am not a fan of the side cut outs as I like to cover my fat, this dress made it easy to tuck up and stay so that nothing was exposed. Highly suggest renting it !! True to size. Great wedding guest dress.

move great, very tight in the waist

unless you have a barbie waist or no extra padding around your midsection, size up. the elastic is really tight and parts you didn’t know could bulge will. other than that, the dress moves great and people loved it
