Bra Builders

Bra Builders is an online retailer focused on helping sewists create custom lingerie. Its shop offers supplies for bra making, along with products for lingerie and undergarments for women, men, and children. The selection includes bra kits, lingerie capsule kits, lace, bamboo and knit fabrics, flexible underwires, channeling, fasteners, hardware, and elastic in a range of colors. Customers can choose complete kits or purchase fabrics and components separately, with featured designs such as stretch lace and tulle lace styles.

The brand also supports makers with learning opportunities and community resources. Its Bra Fit Studio hosts clinics, including seasonal bra-fit events, while tutorials, sewing notes, bra-building resources, and sizing information help customers develop their skills. The Kit of the Month Club offers recurring kits, and the Bra Builder Community provides a place for sewists to learn and share. Whether someone is beginning a first project or refining an established practice, Bra Builders brings materials, guidance, and inspiration together to make personalized bra and lingerie sewing more accessible.
