"I built BOLD Swim because I couldn't find swimwear that fit my body. I built BOLD Undr because every woman deserves underwear that protects her health, doesn't drain her wallet, and doesn't destroy the planet. We have the fabric expertise. We have the supplier relationships. We have the community. The only thing missing was someone willing to build it. So I did."
