Boyfriend want his T-shirt back? Not to fear: the Los Angeles duo of Lauren Alexander and April Leight founded LnA in 2007 just for girls who love menswear basics and that cozy, lived-in feel. Focusing on fit, color and perfect cottons, the designers bring a sexy update to the classic men's undershirt tee: a slim-fitting, semi-sheer top with an extra deep V-neck, available in a covetable range of 30 colors. (When was the last time your boy tried ballet pink?) Quickly winning a celebrity fan base that includes Isla Fisher and Kate Moss, the line has since expanded to include everything from lace tees to that LA signature, zipper leggings. These are wardrobe staples with some edge.
