This dress is stunning! I bought it for a Gala. It's a perfect length, you don't need to worry about stepping on your own dress. It is comfortable & elegant. It drapes perfectly across the side of your shoulders.

This is an absolutely gorgeous dress, and a show stopper for sure. Everything about it shouts class, grace, style, and glamour. It is sparkling in a classy way. I'm 5"6' and the length is perfect. Every lady needs an evening dress in black, and you can't go wrong with this beauty!

★★★★★
This dress is beautiful and very flattering. Fits to size and is flowing and very comfortable with soft material. I was worried the material would get snagged on things but it did not. It is also wrinkle resistant, I pulled it out of the shipping bag and it had no wrinkles.
