Nice dress, just not the one
I wasn't expecting the material this dress came in to be a thick, prom-dress-like material. In the pictures, it looked more like a thinner satin or something. The dress was structured beautifully and fit true to size, but I just wasn't a big fan of how I looked in it.

Bombshell dress!
I wore this dress to a masquerade ball for New Years Eve. RRR emailed me a couple days before my rental to let me know that they could only send me a size 2, which was my back-up to a size 4. I was a little nervous about the fit, but the size 2 still worked really well for me. It was definitely form-fitting, and I felt like I needed to suck in all night, but my boyfriend loved it so that's a plus! The fabric was thick enough and the cut supportive enough that I didn't need a bra. Overall, I felt great in this dress and didn't want to send it back. I definitely recommend it for a cocktail party or formal night out (I would hesitate to wear it to a very formal or work-related event because it does show off a lot of curves).

Event was canceled, but the dress is incredible.
I am usually a 00. The 2 fit perfectly, other than the straps, which were a little bit loose.

I love Zac Posen dresses!
I have rented a few Zac Posen dresses from Rent The Runway, and they have all fit perfectly. They hug in all the right places. I have a smaller waste and wider at the hips so most dresses are really baggy in the waste. These fit like a glove! The top part has a built in bra which was nice. I wore this for my birthday where I was going for an old Hollywood glam look. It was perfect!

The dress was so vibrant and beautiful. It moved with me and wasn't constricting at all
The dress rode up every few minutes to where the zipper was scrunched up a little in the back but that's to be expected with a tight dress. The dress had two layers and both were flexible. The straps however were a little long on me

Loved this dress, wore it for a pin up theme so I used a pencil skirt over it. Amazing color and fit
Loved everything about the dress, very comfortable and definitely eye catching with the red! You won't regret picking this dress!

gorgeous dress for any grown-up occasion
i rented this for a date night out at the theatre. the dress is super elegant and made of a rich, red, sumptuous fabric. there's a little stretch, but it's still structured. i went with the 10 since it fit well around the waist/hips area and i didn't want to get much tighter; the only minor thing is that the straps were a smidgen too long, but i'm short and that's a normal issue and nothing particular to this dress. it's classy yet just flirty enough; it's a great date dress but also would be perfect for a cocktail party or even an upscale work social event. would highly recommend and tempting to rent again.

Amazing dress and so flattering. The order came on time and was prompt.
Dress was perfect for the occasion and a very noticeable red dress. I was not too happy with the tiny thread sticking but honestly no one noticed ( except for me) and I got lots of comments on how beautiful the dress was. It stretches a little and is a great body con dress.

Rented this dress for a company Christmas party. The dress looked great!
The overall fitting of the dress was great and cliched perfectly at the small of my waist. The only con about this dress is the straps were too long for someone my height. I had to adjust them through the night, especially while dancing.

I really loved the material of the dress. It was comfortable and really classy.
I am 5'8" and 128lbs and I wore a size 4. I ordered both, a size 2 and size 4, and the 2 was just a little too tight. Usually Dresses are too short on me, since I have long legs, but this dress was the perfect length and fell right above the knee- perfect for a wedding. I was able to dance comfortably in the dress as well.

This was a beautiful dress and the color was an attention grabber!
This was sexy but not not too much and it hugged all the right places. The straps were a bit too long which made my c-cup exposed more than I normally would have liked.

Definite head-turner! Great for anyone who loves a little red dress.
Pros: It was definitely an eye-catcher! Great color and interesting details. I got many compliments and the dress photographed really well. Cons: It was hard to wear with even a strapless bra as the straps were a little too long causing it to sit low. The top part of the dress sit low enough where i felt like I had to keep pulling the sides of the bra down so you couldn't see it above the dress. It definitely ran small. I usually wear a size 0 and I wore the 2 I ordered as my back-up. I have almost no curves and it was still fitted a size up, so a curvier girl would definitely want to order up.

Stood out in a sea of black at MBA formal event
This dress has been by far my favorite that I've ever rented from RTR. It was a lot more detailed in person and built really well. I ordered the dress in a size 2, which is my usual size but I was skeptical because others said that it ran a bit small (and no backup sizes were available!). However, the 2 was perfect because there was a little stretch in the fabric. I also didn't need to wear a bra or spanx because of the build of the dress. I wore gold heels, diamond earrings, and a gold Kate Spade clutch that you can also find here on RTR. I loved it and everyone else seemed to love it too!

Beautiful dress, runs small
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!

Padded chest makes for a weird fit
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 sexy dress
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.

gorgeous dress!!!
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!

Great color - fun dress!
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!

Loved the color of this dress- it was a last minute switch and worth it.
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!

Great color, great fit
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.

Didn't fit
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!

Great Dress..
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.

The color of the dress is an amazing red and the length is great on my 5 foot height. However the straps are really long on me but prob right on the model I tried to pin it but the straps are very thick so I just dealt w them falling a little

Perfect little red dress for a fancy summer 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.

Killer piece!
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!
JanetJanuary 6, 2015
Danielle!!!! You Look amazing in that dress!!!! I am about the same size and shape as you lol.I had a couple of questions first you said you ahve a fuller bottom, so do I lol Did you love the way your butt looked in the dress, were you able to just wear a regular thong and not have an issue with VPL. Second I am 40 do you think this dress is too short for a wedding at my age? Finally you said your a 34B, girl your boobs look HUGE in that dress lol. I am a 34B also, is the dresses padded in the bust or did you have a great bra if so what bra did you wear lol. Thanks so much you look killer in that dress!!!

Perfect for my sorority's semi-formal!
This was my first time using RTR and I LOVED it! It was perfect for my semi-formal. The dress fit like a glove and it had just the right amount of stretch for my fuller bust. I got compliments all night long.
