Zyrra uses mass-customization technology to solve a widespread problem: It is difficult to find bras that fit. We have a patent-pending fitting system for bras that goes outside the limited '36C' 2-dimensional sizing model. We take 10 measurements (vs the standard 2) and create a unique cutting pattern for each client. A bra is then made to fit those measurements perfectly, delivered by mail within 4 weeks. Each bra comes with a perfect-fit guarantee.
Putting an end to the misery of shopping for bras
