To wear this Carlotta white lace mini dress, just put it on over your chosen undergarments. The adjustable back straps allow you to find the most comfortable fit. Since it's semi - sheer, always wear nude or black undergarments or swimwear underneath. When it comes to sizing, remember to size up because of the lace fabric. For maintenance, hand - wash it in cold water with a gentle detergent to keep the lace in good condition. Avoid wringing it out to prevent damage to the fabric. Hang it up to dry. With proper care, this dress will serve you well through many summer days.
