    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.

    Beautiful stitching and a really elegant design. It feels much more expensive than it actually is.

    Lovely dress
    The zipper was a little stiff the first time, but after wearing it once everything worked perfectly. Overall, I'm very happy.
