Beautiful dress for a formal wedding!
The color was stunning!! Dress ran a little small in the chest. Very flattering, but I'm 5' 9" and even the 6L was not long enough for more than 3.5 inch heels.

RTR Team Review!
I have a very small chest so it was a little big in that area - a strapless bra could have helped create a little more shape to fill it out. The silhouette creates a really nice hour glass shape (even if you dont have one!). The length (and I am 5'5" with 2.5" heels) is just right, grazing the floor. Beautiful rich blue color.

Stand out color!
I had to size down because there was extra room in the hips and I have a small lower half. Fit super well on the top, and did not need a bra.

Did not wear
I was rooting for this one because it was brand new. However, the fit was not flattering on the stomach area. Otherwise, it felt great. Give it a try if you have a smaller mid-section.

Best dress I have ever tried on!!
I rented this dress for a black tie wedding. I went to the store to try on styles. I tried on about 5 before this one and as soon as I did it was a done deal! The fit is true to size. I did wear spanx just to smooth everything out but they weren't s necessity. The material hugs you so nice. I received so many compliments on this dress!! I opted for a simple silver bracelet no necklace and just did diamond drop earrings. Very sleek simple elegant feel. I would highly recommend this gown!! If I ever need another fancy gown I will be ordering this again in the fuschia color! I got tall 5 inch gold heels to wear with this gown but by the end of the night was was in 3 inch wedges. I wish I would have started with the wedges. They gave the bottom of the dress an extra movement when I walked the tall shoes didn't give.

So comfortable
Felt great in this dress. I got it as a back up but couldn't resist wearing it. The material is very comfortable and has some give. The bust isn't cut too low so any bra essentially will go with the dress. I am 5'8 and the dress was a perfect length with 3 inch heels. The dress is flattering with curves.

Incredible Color, Flattering Fit
Loved this dress, I felt so great wearing it. It was flattering yet classy - perfect for a black tie wedding. I received several compliments on the color. The length was perfect with 3ish inch heels. I wore it with a convertible bra with crossed straps, but you could also use a strapless.

So comfortable/ beautiful gown, but too long!
Loved how comfortable it was. I' m5' 8'' and the Long length was way too long for me even with 4 inch heels. The dress was SO pretty, but my husband noted the seams in the breast area came together in a way that it made it look "like I was a little chilly" in certain lighting.... I didn't end up wearing it .

Beautiful comfortable dress
This dress was a frantic back up selected at the RTR store in Manhattan when the original dress I'd ordered didn't fit. The color is vibrant and beautiful and the fit is sleek and gave me an hourglass figure I'd don't actually possess. I could wear a regular bra with racer-back straps and felt comfortable and confident all night. I got tons of compliments at the extremely formal black tie wedding and it stands out beautifully in pictures. I'm 5'9" and the Long was maybe a 1/2" too long in my 3" heels, though it didn't get in my way on the dance floor.

HAWT BLUE DRESS.
This dress was absolutely perfect for a wedding of friends old and new. I got so many compliments and felt like a million bucks. The color is stunning, definitely a eye-catcher especially on tan skin. It fit really well, like a glove without being too crazy tight (we had been eating/drinking all day and I still felt great in it). The long was long, but with heels was just fine. It was a really hot day in FL for the wedding (almost 90) but I felt comfortable in this dress despite the length. And finally, INCREDIBLE backside views. ;)

I loved this dress! The color is incredible in person. The fabric is lighter than I expected, but still heavy enough to hold its shape. It also has a little bit of give so it moves with you.

Gorgeous color and very flattering
What a beautiful dress! This complimented my body shape SO well. I wound up using the other dress in my order for the wedding I was attending, but would absolutely rent this gown again for something else. Highly recommended for women with a fuller bust and athletic build. Do be aware that the long is very, very long. I am 5'8" and was absolutely swimming in it. Go with the regular if you are under 5'9" and/or will not be wearing 4 or 5 inch heels. Otherwise, what a winner of a gown.

Simple yet elegant!
Fit like a glove. I got the long, but didn't wear heels. I'm just under 6 feet tall, and it wasn't too long to wear without flats. If you're on the tall side, I highly recommend getting the long. The fabric was structured and hid any bumps of flaws - I didn't wear anything under it. I got compliments all night :)

Show stopper!
True to form, I left finding a gown for a work gala for the last minute. I ended up having to go to the Flatiron store the day before to find a dress. This dress was not on my radar because looking at the model pictures it just didn't seem like me but then I tried it on and it was an instant love affair. I swore the 2R was not going to fit me. I'm 5'2 130 lbs and curvy and usually wear 4/6 and sometimes an 8. The dress has great stretch and lining so it hugs in all the right places and also sucks stuff in. I swear it made my waistline appear smaller! I wore it with 4" heels and the length was perfect. The royal blue was gorgeous and I got lots of compliments the whole night. Definitely recommend it! Oh the lining is thick so maybe avoid it for a hot outdoor event.

The stylist picked this dress out for me!
I had a summer wedding to attend and originally had a flowy dress in mind. After telling my stylist a bit about the event she picked this out. I tried it on and the rest is history! I didn't even want to try on any other dress. It's well made, not stretchy but will hold you in in the right places. I received compliments allll night and in the end I did not want to take off this dress! If you want to feel beautiful and classy I recommend this big time.

Gorgeous color but not long enough in tirso
Absolutely gorgeous color but not for the gal with a long torso. I am longer in the torso and shorter legs. Had this had 2 more inches length on the top it would have been perfect. As far as length with heels the 4L was great. I could not wear this to the wedding because I need to find a dress that will fit my torso better. Super bummed because otherwise it's perfect.

KNOCK OUT DRESS- BETTER IN PERSON!!
LOVED LOVED LOVED this dress! I never would have picked this one out based purely on how it looked on the model- but I am SO glad a RTR stylist recommended it. I can't tell you enough what a knock out this dress is. It hits all the right places. It's very form fitting, but smooths everything down. The fabric is also pretty stretchy which helps give that va va voom fit. Highly recommend for pear shaped or hour glass bodies. I rented the 4L. Im about 5'10 and I wore 3.5 inch heels and it still dragged a bit. I didn't mind the length, but if you are any shorter I wouldn't advise on getting the long.

This dress is amazing! The fabric, cut, and color together make it an unbeatable fit. I usually wear a size 2 or 4 and don't have too many curves but this dress made me feel like I did. The neckline is simple and flattering. The dress doesn't need much to look amazing!

This gown was a dream!
At first i had rented a gown two days before my event that did not fit at all and so in my panic, i went to the flatiron store praying to find a gown that would fit and look great. i ended up trying on 8 gowns, with this gown being the winner. the gown fit true to size and slipped on like a glove. it emphasized my hips and gave the illusion of a small waist while also showing an appropriate amount of cleavage. i received so many compliments that night i would definitely rent this gown again in every color possible! only negative note is that the dress is pretty heavy and if you are short like i am, you will definitely need to wear sky high heels or hold the bottom all night.

I want to buy this dress!
There is nothing bad to say about this dress - it's beautiful and was perfect for the black tie wedding I went to last weekend. I'm 5'2" about 110lbs and wear 32DDD bra, I rented the 0 regular and with a 4/5" heel on fit perfectly. It was flattering on top and actually minimized my chest (which was the goal!). Material is a bit heavy so not ideal for outside event in summer but overall a beautiful dress :)
