So flattering but size up!

I was nervous about renting this one because of all of the negative reviews, but I really wanted to try it so I did and I sized up one. It worked perfectly! I did wear shape wear underneath to smooth my tummy for the drop waist. So many compliments! And it was also quite comfortable.

Loved the colors and fit

It was perfectly snug through the middle (no trouble zipping) and was figure-flattering for me. Great late fall or early winter dress for work. I will rent this one again.

Works for maternity if you size up

Rented to potentially wear to my baby shower. Ended up not wearing but it’s a beautiful flattering dress and would rent again in the future, pregnant or not pregnant. 33wks/180ish/34D here in the size 46

Pretty

The dress fabric is silky to touch. However not suited for warm weather. There is a long thin slit down the front bodice which shows a bit too much for work. The shape is beautiful. I should have sized up one. Definitely consider for cooler weather like fall.

Being older I have a larger waist but wasn't tight. Gorgeous fabric, fit loose but still form fitting for me.

This one requires sizing up

I always go for a 14 in this one because it is snug at the hips. So the 14 is a bit loose everywhere else, but it works.

I liked this way more than I thought I would! I rented it for Thanksgiving and wore it all winter. Thin material doesn't get too hot despite all the material. Another Derek Lam win!

Great fall dress!

This is a great dress for fall! Looks so cute with a pair of mid or knee-high boots. I wore to work, but it would be fun for a date night or event too. Good length for tall gals!

Gorgeous, but beware of hips

I got my true size and it fit amazing once I got it on. But, it almost didnt go over my hips, and Im pretty narrow. If you are curvy at all, Id size up.

Loved it!! Classy and flattering

Got so many compliments on this dress!! Wore it to two separate events in a row because I loved it so much. The detail, the shape and the drop waist were very flattering. It’s a more conservative look, so pairing it with a stiletto style heel worked great to give it a little the overall look a little extra flare.
