our story
Born from a founder who refused to settle
Twenty years ago, Lisa Ebbing refused to wear nursing bras that made her feel invisible, just because she was becoming a mother. That refusal sparked a revolution. Today, Hotmilk has sold over 2.5 million maternity and nursing bras and briefs worldwide.
