To wear this bridesmaid dress, first unzip the back zipper and step into it. Then zip it up gently. Make sure the sweetheart neckline sits nicely on your shoulders. When it comes to maintenance, since it's made of chiffon, it's best to hand - wash it in cold water with a mild detergent. Don't wring it out; instead, gently press out the water. Hang it to dry away from direct sunlight to avoid color fading. As for sizing, if you're unsure, always measure yourself and compare with our size chart or choose custom sizing.
