Unique stunner!

Size worn: 0
Overall fit: True to Size

This dress is so different! The keyhole cutout and low back make this dress so unique and fun. The skirt runs slightly narrow, so sizing up for the free backup size is key, but there is plenty of room at the bust area. The detailing in the fabric is so beautiful in person, I would highly recommend it!

This dress was awesome, I loved it. The styling and detail in the fabric made it different from all the other black dresses you've worn. The keyhole cutout was a fun feature. I would recommend this dress!

Nice but didn't fit my body

Size worn: 8
Overall fit: True to Size
Rented for: Wedding
Pretty dress with a little touch of sexiness for a formal wedding. I had tried on the 6 and it fit just right at the waist and hips but the top was very loose(for my A cups)... this dress would better fit a fuller bust. I unfortunately made the mistake of eating a very large meal right before the wedding... so decided to wear the 8 for comfort. It was knee length on me. My statement necklace (from a mystery bag item... kudos to the stylist that picked it for me) grabbed all the attention from the dress. It was not the right fit for my body type so would not rent again.

Felt sexy in this dress

Size worn: 10
Overall fit: Small
Rented for: Wedding
This dress is very snug in the waist & hips. It fit, but I did feel like my original size was too small and the backup size was too big. Recommend for people without much shape in the booty. I got lots of compliments & overall was happy with the dress.

Gorgeous!

Size worn: 0
Overall fit: Small

Very pretty sheath, even though the fit was a little odd--the 0 was a tiny bit too small in the skirt, and the 2 was too big in the shoulders and chest. I ended up wearing the 0 and it looked beautiful even if I was a bit uncomfortable.

Beautiful Dress but doesn't fit well

Size worn: None
Overall fit: True to Size
Rented for: Party
Beautiful dress! However, you need a long torso and small hips to wear this dress. I ordered a Size 2 & 4... The size 2 fit fine in the bust but was WAY to small in the hips, and the Size 4 fit fine in the hips, but was WAY to big in the bust. I have a shorter torso, bust is 32D and my hips are semi-curvy...I think this dress is for the straight & narrow body type.

It fits your body really well

Size worn: 0
Overall fit: True to Size

I am sure others pointed out, it lacks elasticity, so 0 was quite tight, but 2 was too large, so I went with the smaller size. The back is completely uncovered, but it makes a sexy statement.

Perfect little black dress for every occasion!

Size worn: 4
Overall fit: Small
Rented for: Other
It's very flattering and the key hole makes it very unique. I am usually a 0 or 2, but both fit exactly the same (TOO TIGHT). So RTR sent me the 4 that same day and it fit a little too big. I think my size 2 was mismarked as a 0 which is why I had some trouble. Either way, I wore the 4 and got lots of compliments!

The fabric on this dress was absolutely beautiful!

Size worn: 6
Overall fit: True to Size
Rented for: Formal Affair
The fabric was really my favorite part of this dress. The subtle print is very intricate. It fit well from the waist down, but the top is cut a little strange. It gapped under the arms but it wasn't super noticeable. A stick on bra is definitely a must for this one!

Sleek and tastefully sexy!

Size worn: 4
Overall fit: Small
Rented for: Wedding
I rented this dress for a wedding and was very happy with it! I absolutely loved the low back but as other ladies had warned, it did run very snug through the hips. I usually wear a 0-2 but after reading other reviews rented the 2 and the 4 and ended up wearing the 4. The dress fit nicely through the natural waist and the hips but I did add teardrop liners to the bust because it was a little too big. Overall, I loved the dress and received many compliments!!

This is a very nice dress but it fit a little bit tight around the hip area. I loved the way it looked overall.

Very nice but very narrow

Size worn: None
Overall fit: Small
Rented for: Wedding
I should have listened to the previous reviewers more closely. I sized up because I read that the dress was narrow in the hips, but the dress was still too small on the bottom. And since I had sized up, it was loose around the top. Definitely for a straight and narrow body type. Beautiful dress and fabric in person.

Beautiful dress - very odd fit

Size worn: None
Overall fit: Small
Rented for: Wedding
The fabric and style of this dress are beautiful - I wish that I had fit into either size I rented! I ordered the 2 and 4 based on previous reviews that suggested sizing up may be necessary to be sure the dress isn't too tight in the hip area. They were totally right - unfortunately, the chest of the dress ran super large compared to the hips and I couldn't have worn either size. This dress would be best for someone with more of a straight-and-narrow frame that's on the taller side and not flat chested. The whole top of the dress was loose on me - even the 2 - so I think I am just too short for this one.

Pretty, but over-worn

Size worn: 4
Overall fit: Large
Rented for: Formal Affair
Dress fit well through the hips, but the top was loose and had faded in one spot, like it had not been cleaned properly. The fabric was nice, and would have loved the cutout if it had fit up there.

just not right for me

Size worn: None
Overall fit: Small
Rented for: Date
this dress runs very tight so if you have hips (which i definitely do) maybe try going up a size. the other reason i didnt wear it is the design on the dress didnt really match the picture. it looked a little more youthful than classy.

Great dress, a little too small

Size worn: None
Overall fit: Small
Rented for: Party
I rented this for NYE - reviews had someone 10lbs lighter then me in a 4 and someone 10lbs heavier in a 6. The 6 wasn't available so I went wit the 4. I was able to zip the dress but it was extremely tight. So tight that I was afraid if i wore it all night it might break. So, unfortunately I had to send it back. Beautiful dress though.

Sexy and Sophisticated

Loved this dress. It runs a little tight in the top if you have a large chest, but I was still able to squeeze into the 6. The rest of the dress is extremely flattering and I loved wearing it out to dinner and the club after for a night of dancing.

Simple with pretty details

Size worn: 6
Overall fit: True to Size
Rented for: Party
The cut and fit of this dress were great. It was comfortable and simple, but had nice details that made it feel unique. The keyhole in front is located in a flattering place, and the black fabric has an embossed flower pattern on it. This is a great dress for a casual work event or party. My one dislike was the thin fabric - less structure in the stomach region made for a less flattering fit.

Beautiful, but very snug in the hips.

Size worn: 4
Overall fit: Small
Rented for: Wedding
I am typically a size two, but sometimes a four because I have wider hips. The four was very snug on my hips, but loose on the top (I have a smaller chest). Because of the fit, I was debating wearing it. But after some thought I looked at the positive: it really emphasized my curves and made me feel sexy (from the front/back - not too much from the side). I do wish the the fabric had a little more give though so I would feel more comfortable.

This dress was fun and added some vavavoom! Not your typical boring lbd.

Size worn: 8
Overall fit: Small
Rented for: Wedding
The dress, for the most part, was pretty comfortable. A bit tight on the waist, but works well for a larger chest. The skirt was also rather form fitting, which made walking up steps a bit difficult. The straps were a bit longer, which meant more of the area under the armpit is exposed. If you tend towards having back-fat, I advise against wearing this dress. Pros were that I was still able to wear a normal bra with this dress. Only had to make sure the bra stayed below the back a few times throughout the evening.
