This dress is GORGEOUS! I usually wear a 0 or 2 and the 0 fit perfectly. I am 5'4 and it hit mid-thigh. It is very flattering and a beautiful shade of red (FYI the chest area is padded in this dress). I think it is sexy and classy at the same time (although it could get really busty really quickly if you have a larger chest because of the padding).

I loved this dress! It was really beautiful, and I received tons of compliments on it! The only thing that kind of bothered me was the fit. It was a little tighter than what I normally wear, but that didn't stop me from wearing it!

Someone told me it looked like the dress was custom fit...

Overall fit: True to Size

This dress was beautiful. It's much more sturdy than I imagined it would be, and it's stretchier as well. I was worried I wouldn't be able to dance (was in Vegas) but I could get low no problem! I'm also not busty, so I was concerned it would look "empty" on top. It didn't. It's flattering and the color was definitely bold. Wore with some dark gray wool CL pumps (red bottoms matched the dress perfectly!)

I loved this dress! I am a really short girl, so it can be difficult to find dresses that fit me well, especially because of the length. This dress was a lot longer on me than it would have been on most, but that made it perfect for dancing! I loved this dress!

I loved this dress! It fit beautifully and hugged my curves perfectly. The color is very bold and the dress was stretchier than I expected, which was a plus because it allowed me to dance comfortably all night. It was the perfect party dress.

This is a great dress. The top is padded and helps keep everything in place without a bra- yay! The hips have a snug but flattering fit. Stretch in the fabric allowed for sitting and movement. I had a fun night out in this dress. The fabric is nice, but feels slightly unrefined...

Between the color and fit...DEFINITELY an attention grabber!

Size worn: 6
Overall fit: True to Size
Rented for: Formal Affair
I usually wear a size 4 because while I have a smaller waist my hips are slightly larger but since this dress doesn't have much give in the hips I went with my back-up size 6 and it fit like a glove! I wore a strapless and padded bra and the cut up top was sophisticated enough to wear to a work formal. The length hit me an inch or so above the knee...long enough to wear without stockings in my opinion. This was my 3rd RTR dress and my favorite by far!

"You look hot!"

Size worn: 6
Overall fit: True to Size
Rented for: Wedding
This dress was definitely a hit, and I received so many compliments on it. I liked how the material had some stretch to it because it allowed me to dance all night. The only things I didn't like about the dress are that the cups are very padded (wasn't expecting that), and the fact that I had to wear a strapless bra with it. Both of those things didn't take away from the dress, but they're just something to think about. Overall, it was a great dress for my first rental.

Pros - Shows off your curves, flattering for the bust, slim fit around the hips. Cons - straps kept falling off my shoulders and I had to keep pushing my bra down so it didn't show

I ordered both a 0 and 2, good thing i asked for the 2 bc the 0 was way too tight. I recieved plenty of compliments so i guess it was a hit. I just didnt love the red for a spring wedding, but that was my fault, in the winter it would be perfect!!!

I absolutely loved this dress! The size 2 was a little snug from the waist down (I have a fuller bottom), but the material is pretty giving, and it fit perfectly up top. I thought it was a great color for a winter wedding and I felt super sexy and comfortable dancing in it all night long. Highly recommend!

Perfect little red dress for a fancy summer wedding

Size worn: 6
Overall fit: Large
Rented for: Wedding
Fantastic dress! Loved the details on the straps. Runs large in the bust, but because of the style and padding it's not noticeable. The fabric is stretchy so it was great for wearing a fitted dress that I could dance in all night. Received a ton of compliments, whenever I rent from RTR I know I'll have a quality garment that'll look fab.

This is a great dress. It's vibrant color will sure stand out in a crowd. The fit was great. The top bodice fit a little funny, but it was definitely manageable. I'm pretty short, so I temporarily hemmed the dress with fashion tape. It worked very well. I would rent again.

I wasn't able to wear this dress unfortunately. I got a 4 and a 6 (normally wear 4) and both were way too tight in the hips and tummy. Might work better for someone with a straighter figure! It was a shame because it was beautifully made and nice material!

This dress fit me great, it has a little bit of stretch to it, so although it was tight, it was easy to walk in. I rented it for a weekend in Vegas and got tons of compliments. Its a classy dress, good length but I'm short so tall girls might find it too short. I'm also not very busty and went bra-less with this dress, if thats not you, it might not be as good of a fit.

I was probably a size 2 at this time but I ended up wearing the 6. Definitely runs small, the 4 was just too snug through my hips. I was originally wearing a Herve Leger bandage dress but decided to go another way. I wore this for an onstage question and I got so many compliments on the dress. Amazing in person!

Loved that this had built in support so I didn't have to wear a bra. I always wear a 2 but this one was a bit snug - a 4 would've been a bit more comfortable, but at least the material had a little stretch. Great standout color and perfect for Vegas cocktail party!

Wore this dress to a sorority charity gala and it was PERFECT. The color was a little darker than it looked online, but definitely a true red. The bust is pretty padded so I didn't need/miss a bra and even at 5'10 and wearing 4-5 inch heels, it wasn't too short! The straps were a tinyyy bit loose (wasn't an issue at all for me, but I would imagine with a shorter torso it could be). Wish I owned it!

Size worn: 4
Overall fit: Small

Got tons of compliments! Fits beautifully. Could not recognize myself in the mirror. The dress is of a darker red in person. Runs small! I usually wear 0 or 2. Ended up wearing the 4, for extra movement. Both 2 and 4 actually fit well, but I wanted a little bit more room at the hips. However, the shoulder straps kept falling off my shoulders in the larger size.

There is pretty significant padding in this dress which I definitely do not need and made for a weirdly top-heavy dress. For smaller chested women, I think this would probably be very nice.

Beautiful dress, runs small

Size worn: 4
Overall fit: Small
Rented for: Formal Affair
I wore this dress for an event for my husband's company, and it was very appropriate. Not too short, not too low cut, but still very figure flattering. It's a beautiful shade of red and luckily the dress has stretch to it because it is tight. I usually wear a size two, but I couldn't even get the 2 over my hips! The size 4 was just able to get over my hips, however the straps up top were a bit loose. So although it wasn't a "perfect" fit, I still felt beautiful and confident in it. The process couldn't have been any easier and I will use Rent the Runway for every event I have from now on! I can't wait to order another dress!
