This dress was everything the reviews said - nice weight, well made, and great fabric. The suggested size matched my usual size, and it fit like a glove. That said, there was no extra room, and the fabric has no stretch. I’m 5'9" and prefer long dresses to be closer to ankle length, but this one hit at an awkward length on me. For the price, it wasn’t worth keeping, though I do think it’s fairly priced for the quality. Nowadays it’s hard to find clothing in cotton or cotton/linen blends, so I really appreciate that it’s not made from synthetic fabric.

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.
