What is an Alteration Seamstress?

An alteration seamstress adjusts clothing so that it fits a person’s body more comfortably and looks more polished. This specialist works with existing garments rather than creating new ones from scratch, using sewing knowledge to improve how clothes hang, move, and feel. The purpose of the role is to help people get the most out of the clothing they already own, whether by resizing, updating older pieces, or making small changes that create a better fit.

Alteration seamstresses are commonly found in clothing boutiques, bridal shops, dry cleaners, department stores, and independent sewing studios. Some also work in theater, film, or fashion production settings where costumes and wardrobe pieces often need adjustments. Success in this career relies on steady hands, strong attention to detail, patience, and the ability to understand how different fabrics behave. Communication skills are also important, since the work often involves discussing fit preferences with clients and offering practical recommendations.
