Dressmakers measure customers to get measurements for garments. Once the dressmaker has the customer's measurements, the process of cutting fabric and sewing can begin to assemble the clothing. Dressmakers schedule a fitting for customers to try on the clothing and make notes on alterations. Some dressmakers offer customers alterations on existing garments. A dressmaker may specialize in a type of clothing such as wedding dresses or work with a designer to create clothing from designs.
