TomboyX, the Seattle-based startup bringing gender-neutral underwear to the masses, is apparently a good fit for investors, too, as the company just closed an $18 million Series B funding round. Launched in 2013 by married founders Fran Dunaway and Naomi Gonzalez, TomboyX targets “plus-sized, gender non-conforming and specialized tradespeople” with its apparel products. The company raised $4.3 million in a Series A round last summer, and total funding is $24.3 million to date.
