Find the right fit: A bridesmaid dress is typically ordered using a person's biggest measurements (from the bust, waist and hips), so your friends will likely buy dresses at least a size larger than they normally wear. If a friend wants to buy a size smaller, let her know it's much easier to alter a larger dress, and if the dress ends up being too small, she'll likely have to order a new one and you'd hate for that to happen.
Ordering etiquette: It can sometimes take up to six months for orders to arrive and four to six weeks for alterations. A six to eight month cushion will give you and your friends ample time to find and order the dresses and get them fit.
