Nicely lined. Fit like a glove.

Beyond obsessed with this dress. Some reviews said it ran big so I got a size 2 and 4, I ended up going with the 2. Wore it for a November wedding. There is a nice light lining inside that helps the silky exterior lay flat and not hug in the wrong places. Good for a small chest and pear shape. Very comfortable and easy to dance in. I received so many compliments.

The most stunning dress

I felt like a bombshell in this dress!! Got so many compliments and was just overall so comfortable! Make sure to wear the right bra, besides that, be ready to shine!! I got my size a bit larger to ensure it’d fit and the size worked perfect! It wa sa big large but ir helped the flow of the dress

Beautiful deep navy color!

This dress is s winner! I am a size 8 in most dresses and I chose the size 8 (regular length) here and it was perfect. For reference, I'm 5'9" about 160#, 34DD chest. The deep v in the front of this dress is definitely a bold statement but it's a beautiful fit and definitely encourages you to maintain good posture the entire evening. :). I did not use fashion tape but I read other reviews where fashion tape might help keep everything in check. I posted photos for reference - from the side view it might look like some of my chest if popping out a bit but it wasn't, that was just the angle. I tried to post one photo with a view from the front so you can get a better idea. I highly recommend, the color was gorgeous and fabric hung perfectly.

Gorgeous dress. Lots of complements.

The 6R (XsR) was ok throughout, but was quite a bit shorter than the 8R (SR) & wouldn’t have been as comfortable. I’m 5’5” & would’ve had to wear flats with the smaller size. I wore 3” heels with the larger size & it was great. Would wear it again.

Eye catching elegant dress!

I’m 5’0 and the petite version fit me perfectly! Also a size 4 and I felt like this wasn’t too loose but also not super tight. Might’ve been able to go tighter but I liked the lightly loose fit. Got so many compliments on this dress! 10000% recommend

Dozens of compliments. So flattering and the navy tone was so classy and understated. Long enough to walk and dance in! A beauty of a gown obsessed.

Silky smooth and gorgeous color!

I wore this at a fall wedding in Corfu! It was so comfortable and fit me well. It is DEEEP v but fit my chest nicely. Only time I had to be careful was when I was dancing.

Surprisingly good

My original dress wasn’t going to make it so I had to panic pick a dress the day before. This dress wasn’t simple, sophisticated and fit great. I was worried it would be a thin satin but it wasn’t and laid beautifully.

Anniversary dinner

Loved this dress. The straps were long for me since I’m short waisted so i did pin them. I needed to shorten about 2 inches. i usually wear a 2 but believe the system recommended this size 4 and i usually rent thar way.. i could if maybe wore a 2 for better strap size but it was unavailable.. Beautiful satin material and was super comfortable.

Beautiful material

Felt effortlessly elegant, I initially felt it was too big and was disappointed. I could have definitely worn a few sizes smaller but it wasn't available and I decided to try it with my shape wear adding a little curve to my typically flat backside it was perfect! Fancy and comfortable !

Compliments all night!

The top was a teeny bit too large for my smaller bust - but it worked. I have an hourglass shape, so sizing down would have made the dress too small for my hips. Loved this dress!

Wore this to a wedding and loved it. The top is a bit loose so need to watch out for nip slips. Got tons of compliments.

Perfect dress

Perfect dress. Very flattering. Not too tight on the stomach area so there’s some leeway with comfort sitting and standing. The top isn’t as low cut as it might look but it’s a great balance and didn’t move around too much

Loved it!

Should've gotten one size down so that the bust area could fit better but was in a crunch and RTR didn't have the size I needed. To avoid a nip slip, I ordered a navy shawl/cape to go over it. Overall, would purchase again! Made me feel very sexy and the loose fitting from waist down draped perfectly around my body.

Wish it had petite for all sizes

I got the 12R. The dress and material is so classy and elegant. I rented it with the intention of wearing to a wedding, and with a little more time and planning on my end, it could have worked out. Unfortunately, the straps were slightly too long in the back, so that created a big of a gap around the chest. My friend later told me about some “strap clips” that I could have used to tighten the straps in the back so that it fit better. I am also larger-chested and would have needed to use some boob tape. So, if you are petite but this dress doesn’t come in petite for your size (it doesn’t for size 12 at the time of my rental), you could potentially still make it work, but may not be great for a last minute option. Length-wise, I wasn’t too worried about it as I think with my block heel sandals the length would have been fine. Super classy yet sexy dress though.

I’m 5’2 and rented the 6P, the dress fit perfectly except that it was too short.

The hem hit above my ankles.
