Chiffon Bottom & Lace Top Bridesmaid/ Prom Dresses

I recently got married and we ordered 2 different sets of bridesmaid dresses. These 6 dresses have never been used and they're all size 2. The color of the dresses are between a gray and/or silver. At night the bottom fabric shines. We got very simple dresses. The seamstress said the top lace on the top could be taken off so it could be left as a sweetheart neckline and the ribbon in the tummy could be put higher up and/or thinner and the top could be embellished. Its a true size 2.
