Disappointing second one with a damaged zipper
Size: Medium, Color: Iceberg Green
This is maybe the 5th Drop linen dress I have purcahsed different version for my two girls and I and this is the second one I have received with a damaged zipper. It is disappointing they fit well and are well made . I am not sure if the last two I have received were returned items.

Nice quality
Size: XX-Large, Color: Black
Very nice fit and material. I’m a size 14 & the XXL fits well - maybe a tad bit big, but I didn’t want it to be fit uncomfortably tight either. My only complaint is that the side zipper gets stuck right where the pocket is. But I am able to put the dress on without having to open & close the Ipper.

Gorgeous
Size: Large, Color: Black
I bought 2 of these dresses, they are adorable. They are well made, fully lined, quality product.
They fit so well and will be flattering on any figure.
I’m 5’10”, the length is perfect. Well below the knee.
A classic fit and cut

Flattering fit, great feel, totally worth it
Size: Medium, Color: Black
I had to squeeze my girls in, but I made it work, lol! This was my first time shopping from The Drop and I was so suprised by the quality. It's definitely a heavy dress but I really love how it feels and fits on my body. For context, I ordered a medium, I'm 5'2", 155 lbs, 36DD, and 30in waist. It's tight on my bust but comfortable around my hips and waist, which isn't a big deal. The side zipper kills me though lol so beware, lots of twisting to get that thing shut. BUT still worth it. great dress.

Great dress!
Size: 3X, Color: White
I had to go a size up in this for the chest area. But this is a great dress with adjustable straps. Can do a lot with it. Feels and looks quality!
