Karen Patwa
Age: 33
School: Friends Seminary, Manhattan.
Subject: Math and physics substitute, grades 9 to 11.
Other life: Designs clothing and lingerie for Dangerous Mathematicians, her Lower East Side boutique.
Style: A little rock and roll, a little European, a little S&M.
What this has to do with math: "Math is sexy."
Sure, but what else: "One skirt incorporates a concave-down parabola. But mostly it's about taking women's intelligence and bringing it to fashion."
School Uniform: "I like to wear my Princess dress, which has sexy lacing up the back. But I wear it with a jacket or sweater."
