When you receive your lavender tulle bridesmaid dress, try it on right away to make sure it fits well. If you ordered a custom size, double - check the measurements. For everyday wear before the event, be careful not to snag the tulle on sharp objects. When it's time to clean the dress, it's best to take it to a professional dry - cleaner to keep the tulle looking its best. Store the dress in a cool, dry place, and you can hang it up with wide - shoulder hangers to maintain its shape.
