This season's trendy long coats work so well it doesn't even matter what you have on underneath. (Read: grungy sweatpants/pajamas, be damned!) With life much more complicated these days, I welcome this kind of one-and-done, outfit-making wizardry, particularly these options from Stand Studio, above and last pic, Prada (immediately below), The Frankie Shop, OOF, and The Row.
