Perfect Bachelorette Party Dress!

Size worn: M
Overall fit: Small
Rented for: Party
I wore this to my Vegas bachelorette party, for the night when the girls all wore black dresses, and I wore this white one. This was perfection! The material holds you in, no bra needed either. It really shows off curves and made me feel amazing! Super comfortable to dance in all night also! Glad I went with a size up after reading reviews that it is short. I'm 5'2" and the medium was about as short as I would comfortably get.

I had a TON of compliments on this dress!!!!

Size worn: S
Overall fit: True to Size
Rented for: Party
I was surprised I liked the small but the material and pattern is flattering. It IS VERY low cut in front, i have a very small chest and even the stickies would show, so i was able to pull the back of my strapless low enough not to show and then use dress tape on the front to keep the dress where i wanted it on my bra. Overall was a ton of fun, easy to wear, gorgeous dress.

I liked this dress a lot. However, because of my short torso I don't think the open back looked that great. Also, don't forget back tan lines! The dress zips up to below a bra strap which was another issue for me. I would rent this one again!

Not a good fit.

Size worn: L
Overall fit: True to Size
Rented for: Party
Not a fan. The material is soft like a jersey t-shirt, and that's the best way to think about this dress. It wasn't form fitting (aka doesn't suck you in), I had to pull it down a lot because it was riding up while walking and scrunching up while sitting...which isn't an attractive look. The cutout hits your back with your bra strap in the direct center. As a somewhat smaller chested girl, I couldn't even just not wear a bra because the jersey-like fabric made my boobs look saggy. Had to get creative with pasties. Sad because I was pretty excited about this dress.

Was a little tight in the bust, and the white made it a little unforgiving across the belly

Looked amazing! Wore it with NuBra which I recommend because you can't really wear a traditional bra with it. A little short but that's what I was going for!

White Hot!

Size worn: S
Overall fit: True to Size

I rented this dress as one of four looks for my engagement photo shoot. For our Chicago skyline shots, I was envisioning white, form fitting, yet elegant, but still a touch of sexy; and this dress nailed it. It's not a solid white, it is textured and stretchy and would fit most body types. The back has a cute cut-out as well. The only thing keeping me from giving this 5 stars is that the bust darts are slightly pointed. Not like Madonna or anything, but I was a bit self conscious; however, I had nothing to worry about as you cannot notice in the photographs. Who ever said you can't wear white before Memorial Day, obviously hasn't seen this dress!

I wore this dress for a weekend getaway with my husband to Vegas!

Size worn: L
Overall fit: Small

The Pro of this dress is that it can definitely be very flattering and was very comfortable. I am a rather curvy girl and the dress was snug in ALMOST all the right places. The Con would be that I couldn't wear a bra. I am a bit busty and even with tapes, I didn't feel that secure when I leaned over. This dress however impressed my husband and I felt sexy and gorgeous in it. I think that wearing spanx would have also helped me with my fit in the dress but its my fault, I was lazy.

PERFECT bachelorette dress

Was a little concerned that this dress wouldn't give enough support, but I was able to wear a backless bra and it worked perfectly. The dress is super comfortable and perfect for going out. Rented a Herve dress for my bachelorette dinner and then changed into this for shenanigans. Awesome dress. May rent again!

Awesome dress!

Overall fit: True to Size

This dress was a total hit when I wore it out for NYE. It was a showstopper and I felt awesome in it. As far as functionality, it acted like a bodycon dress (so it does cling to your curves) but I never had to worry about it riding up during the night, even while I was dancing and walking around. Since I'm petite, I am always worried about length and neckline with dresses, but this was perfect for my shape and size. I wore a NuBra with this too, and it worked perfectly. I'd totally recommend this dress for a petite girl like me!

Didn't wear this dress

I ended up not wearing this dress, while it fit okay, the other dress I had rented fit better, looked nicer and was better for our engagement photos. Since there was only small and large available when I rented, I got both just in case, and the small fit okay, but the large was HUGE. I think I would have been more inclined to wear it if I could have rented a medium.

Used this dress on the last night of my bachelorette weekend in Vegas. Fit was fine but a little on the tight side. Dress was simple and cute but I didn't really like the material, which kind of felt like a stretchy towel.

I wore this dress for a girl's night out in Vegas...it's cute, but definitely very casual and the material is starting to look worn. I would not recommend this dress for anything other than a girl's night out or a date night.

Hard to find a bra that works with it but a low back strapless is good. Def needs a bra if you're bigger than a B...

I know each designer is different, so I suggest you order a size up! It can get a bit tight in some areas, so invest in some spanks too. I loved it and my friends loved it! Felt super sexy the whole evening!

Stunning Little White Dress!

Size worn: S
Overall fit: Large
Rented for: Vacation
I've rented this dress to test out for my bachelorette weekend. I wanted to try it ahead of time, to make sure it's perfect. The dress itself, once on is very pretty. The material is kinda weird, sweatpants-like, which I wasn't expecting. I could tell in the models photo that the dress is textured, which appealed to me. However, there is zero structure to this dress, it's basically like a fitted, sweatsuit. The top with the sweetheart neckline and wide-set straps is very flattering. If you are trying to hide any "problem areas" this dress isn't for you, since like I mentioned there is no structure ie., nothing to hold you in. All said, I will be renting this dress again!

Perfect bachelorette party dress.

Size worn: S
Overall fit: True to Size
Rented for: Party
The dress was perfect. I danced in it all night - a mix of salsa, bachata and hip hop - it did tend to ride up a little, but just under the bum so it didn't show anything. The material is thick and flattering and would fit most body types well. Since it's backless you really can't wear a bra. It is lined so you can go without if you want to. I bought a stick on bra from target. If you're smaller chested like me, put the stickies on in a mirror so they are even and move them a little toward the outside (more toward your armpit), so when you clasp it in the middle it pulls you together and gives you some cleavage. I used double sided dress tape to hold it in place over the stickies. Everything stayed put all night. Overall, classy and sexy dress, perfect for any bride to be.

I wore this for my bachelorette party. I had originally picked a different dress but it didn't work out. The staff at RTR was so helpful in sending me this dress on the morning of my party! That made me very nervous but it ended up working out perfectly. I loved wearing this dress. It is form fitting but a stretchy sort of material. I felt comfortable wearing this all night. I didn't end up wearing a bra because of the open back but you couldn't tell. I recommend this dress for sure!
