> EBY is a direct-to-consumer seamless intimates brand selling wire-free bras, bralettes, and seamless panties for everyday all-day comfort. Co-founded in 2017 by Renata Mutis Black and actress Sofia Vergara, the brand is known for its patented Softwire technology (lift and support with no metal underwire), a 100% Fit Guarantee, a VIP subscription program, and a "Panties With Purpose" microfinance mission that channels a portion of every order into loans for women entrepreneurs in developing countries. Brand voice: "Bras Shouldn't Hurt." "Marriage Is Optional. Good Bras Aren't." Customer service: 888-848-1454, seamlesssupport@join-eby.com.
