A seamstress is a person, traditionally a woman, whose job involves sewing clothing and other textiles. They are trained in a variety of techniques and can create a wide range of items, from custom clothing to specialized garments like medical scrubs and uniforms. The work of a seamstress requires both technical skill and creativity, as they must be able to follow patterns and designs while also making adjustments to ensure a perfect fit. Seamstresses may work independently or as part of a team, collaborating with designers, pattern makers, and other professionals.

While the terms "seamstress," "dressmaker," and "tailor" are often used interchangeably, they refer to distinct jobs. A seamstress sews seams in clothes using a machine or by hand, while a dressmaker makes custom clothing, and a tailor alters clothes to fit a specific person.

Seamstresses work with a range of tools and equipment, including sewing machines, fabric cutters, and irons. They may work with a variety of fabrics, such as cotton, silk, or wool, and may need to adjust their techniques to accommodate different fabrics. In smaller settings, such as home-based businesses or small sewing studios, seamstresses may have more control over their work environment, including their own dedicated workspace and the ability to set their own schedule.
