To wear these bridesmaid dresses, simply step into them and adjust the straps for a comfortable fit. Since they are fully lined and have a built - in bra, you don't need to wear extra undergarments. When it comes to sizing, check the size chart carefully. If you choose a custom size, make sure your measurements are accurate. For maintenance, dry clean these satin dresses to keep them in good condition. Avoid getting them stained, and store them in a cool, dry place when not in use.
