Received so many compliments! TTS. Waistband is a little snug due to elastic band but stretched with wear

Showstopper!

Everyone complimented this dress - it was beautiful! And very comfortable. I wore it to a fancy outdoor dinner. I thought I would have been worried about the midsection split, but it was easy to adjust bigger or smaller per your level of comfort!

Comfy versatile dress!

Has a big waist cut out but being pregnant I just pulled that up to my ribs to be more comfy & hide the cutout!

Team RTR Review

This Peter Som One Shoulder Midi Dress made me feel very festive! I wore it for a Cinco de Mayo party. In my opinion, it runs true to size. It has the versatility of wearing the top part on or off the shoulder. In addition, with the cut out in the ribcage area, you can make the opening bigger or smaller according to your comfort level. The elastic areas provide stretch accordingly and the rest of the dress provides a flowy feel.

Fun, tropical one-shoulder cut out dress

I don't usually wear cut out dresses, but this one is subtle (and you can make the amount of skin showing as wide or as narrow as you want.) It's a perfect dress for tropical trips. The XS fit me fine once it was on, though it was a bit tricky to get off.

Cute dress

This dress was great! I was able to wear a strapless bra, which was really helpful. The skirt is lose and flowy and the color pops. It has a good stretch and I didn’t feel constricted at all. I probably could have done a better job posing this dress because I don’t think I’m doing it the best justice here.

So bright and comfortable

We might’ve been the only people in London wearing color, so the colors in this dress popped extra. It wasn’t too squeezey around the waist or the arm, and allowed me to go braless. The fabric had a lovely flow.

Best dress!

This was my favorite dress I ordered for vacation! I got so many compliments on it. Fit was perfect even though I'm only 5'3. The waist was stretchy and you can adjust how wide you want the cutout to be. Would wear this dress over and over again if I owned it!

Comfy fit with classy style

The fabric was light weight and not wrinkly- nice for mild to hot days. It was super easy to throw on and look dressy. The fit is TTS and you could adjust the cutout to be as big or small as you’d like. I wore a sticky bra and the fit felt like it could work for many different sizes up top. I rented this with my membership as a “maybe I’ll like this”, but ended up liking it more than the dresses I was very excited to wear. If only there were pockets, this would be that perfect dress.

Great fabric and stretchy

The dress does not have any zippers. It’s just elastic so it’s very amenable to fitting everyone. The material is really long and flowy and very beautiful and soft. Great for the summer. All of my colleagues gave me a lot of compliments. The cut out isn’t as flattering on me, but maybe for someone slimmer.

Super soft material that doesn’t wrinkle. I wore this to work with a white blazer, then on a wine tasting weekend and let a friend borrow it for a party. It was fun, flattering and versatile. Loved this one.

Perfect fit, so many compliments!

This fit true to size, no bulging at the cut out. Lovely wrinkle free material, not sheer (even the white floral pattern).My husband loved it and I received so many compliments! I felt so confident and fun wearing this out, decided to keep it.
