Perfect for a summer wedding

I wore this to my cousin's wedding and felt amazing all day. The fit was exactly as expected, and I received so many compliments. I ordered my usual size S.

Beautiful dress

Really happy with this purchase. I only wish I had steamed it before trying it on because it arrived with a few wrinkles from shipping.

Worth every dollar

The quality surprised me. The material has a nice weight and doesn't feel see-through at all. I'll definitely order another style.

Runs slightly roomy

I was between sizes and ordered the larger one. It still looked great, but I probably could have gone with my usual size.
