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.
