      “Negative Underwear was founded with three words in mind: minimal, considered, and uncomplicated. That's exactly what its bras are."  

      I'm obsessed with your underwear - the only thing I want to wear since I bought them. They're super comfortable and still feel so sexy.” 
      Hayley, 34D + Medium

      “The result is four simple styles produced with premium-­quality cotton and nylon elastane sourced from Belgium and the U.S.”
