We love the Ms. & Mrs. Minimergency Survival Kit, with 16 (count them) super-small essentials—deodorant, hair spray, nail polish, even remover—squeezed into a 3 1/2-by-2-by-2-inch case. It’s perfect for the girl on the go (and, yes, there’s also a Hemergency kit). Buy it now at the T+L Store, inside New York’s JFK, as well as at San Francisco International Airport.
