This dress fits like a glove and is so unique

Fits true to size, I think a smaller bust works best,the fabric is a great semi stretchy fabric and I could go braless without any worry. Easy to dress up or down! I got tons of compliments! A fabulous little number !

Cute dress. Flattering. Uncomfortably short however if you run long in the torso.

Cute dress. In retrospect, I might have held on to it for an evening dress rather than for a day time excursions. It was way to short for me personally, so I probably won't be going back for seconds. But overall it was flattering.

Sadly couldn't wear this. But want to try again!

I love this dress. The 6 was baggy in the skirt so the material bunched up. I'm not small hipped so this dress runs big. I'm hoping to try the 4 and it will fit! Beautiful color and great style. The cut outs are not too revealing.

Awesome dress for Vegas!!!

Rented this for a night out in Vegas. The cut outs make this dress HOT, but tasteful. Fabric is thick and stretchy, so no need to wear a bra or Spanx. I got a ton of compliments from everyone, including strangers. I will most definitely rent this one again!

I wore this to a bar and dressed it down with cute flats since I was on Bourbon Street! This dress was so comfortable and so cute. The fabric is very forgiving and stretchy. Loved this so much, will definitely wear again!

Cut outs were fun yet classy!

extremely comfortable material and the cutouts were surprisingly very flattering. I wore to a bachelorette party in Chicago and it was perfect! I also had a cast on my leg at the time it was great with that! The length was good but I thought it did run a little large so if you are between sizes I would go with the smaller one.

Birthday, it's my birthday!

I originally ordered a different dress that didn't work out so got this as a replacement. I loved this dress. They only had a medium so it was a little big and I could have used a small but I taped up the bottom of the dress and it worked out perfectly. The material is think and lays beautifully. I wish I owned this dress. And props to rent the runway for fixing a crummy situation and making my birthday perfect!

Fun option for summer concert

This dress was super comfortable and the fabric was perfect- just enough stretch and thick enough to forgive the problem areas. The slits showed just the right amount of skin and the length was just the right amount of shortness. Super fun and flirty!

Perfect for Fourth of July!

The fit was comfy and so forgiving. If you have a little tummy the dress poofs out at a very idealistic spot which makes it extremely slimming!

Most comfortable and flattering dress!

First of all My boyfriend picked this out for me to wear and I was worried it would be showing too much skin for a wedding, BUT I wanted to keep this dress on forever. This photo is actually the next morning when I wanted to wear it to breakfast too! I have a very athletic build so I'm lean but I weigh a lot. This is the S and fit great! I could tell the medium would've been fine on top but really frumpy on the bottom half. I have big hips so this fit well and I wore spandex underneath to make it even more comfortable! I wore this to a wedding and although the material feels thicker than I would've expected I was not sweaty from it. We don't dress up too often and I wanted to stay in this dress for days! LOVE this dress and would BUY it if I could and never take it off! :) Oh and that's my dog- she likes to pose for photos. :)

Standout color and cuts

The dress arrived a little worn looking but that did not show at night. The zipper did not lay flat on my booty. I received a lot of compliments and thought the dress looked great from the front. Be careful how you stand as my fat bulged out a bit in pictures when I angled my body to the side.

Perfect dress for Vegas! True to size and very durable fabric.

The fit was perfect. The RTR photos show a lot more skin, in reality there was a lot more coverage of my abdomen and back. The fabric was like a sweater, but it was 112 degrees Fahrenheit in Vegas and I wasn't too hot! So it's breathable. Loved it!

All blue!

Dress was beautiful and material was thick although not warm at all - I have a short torso and it fit just fine - although a longer and taller body would fit best Cute for casual day out in Miami

I felt confident, sexy, thin, flirty. Loved it!

I can't believe how comfortable I was in this dress given how much skin I was showing around the middle. I would have given it 5 stars except that the collar/neck seemed stretched out or low. It was weird. Not noticeable to others though. As others have stated, the color looks a little faded but also not noticeable to others.

Comfortable dress

Really comfortable fabric, also very thick fabric. I felt like the neck was too long for someone my height, I felt my breasts would fall out of the armholes so I did not wear it. Otherwise I loved it

This dress i feel will work with most body types. The fabric is thick and stretchy and the design is flattering/slimming. Not too tight. Very fun and flirty. A bra is not needed. Perfect for a night of dancing!

This dress is very cute. The material is so forgiving. I did order a medium because that was all that was availble but a small would have been much bigger. The dress kind of hung off of me. So cute though

Fun Weekend Dress

Fun dress for weekend or casual wear, but would have liked it better if I didn't have to wear a strapless bra. I THOUGHT I could wear it with a racerback bra, but the front is cut too deep so the straps showed. Would probably be better for those with a smaller bust as I found myself adjusting the top piece several times during the day. I wore it with a mid-heel, but it would look great with flat sandals for a more casual look. The fabric is stretchy but thick so it holds its shape while being very comfortable.

Cool Vegas dress

I rented this for a girls trip to Vegas. I didn't end up wearing it as I went with another option. However, I liked the fit and flare of the dress. The cut outs were fun and the color was a cool blue. I'd rent it again for a fun night out.

flirty, fun short dress but runs large, size down

very thick material, so will hide any problem areas. the cutouts don't show as much. Im 5"5 with a long torso and the cutouts looked like slits not as it did on the website.

Runs large but cute

Rented this for a girls trip to Nashville. Ran a bit large and was longer than I hoped. Flattering fit but wish I would have gone with the XS. Almost looks like denim but is a soft cotton-like material. However, the material is on the thicker side, so it's more forgiving.

RTR Team Review

Awesome cut-out style, perfect for a night out! Running on the small size, we recommend sizing up for backup. I don't typically love cut outs that hit at the hips, but this dress was surprisingly flattering! The material is thick and has a good amount of stretch allowing for you to go braless or wear a nubra, but the minimal bust support makes this dress best for cup sizes A-C. Hips are fitted, so definitely size up if you're curvier. At 5'7" the length hit at about mid thigh. Pair with wedges and gold jewelry.
