The problem with the plaid trend, is that if you don't watch out, it could end up looking a bit teenage boy. Tartan shirts are to be treated with caution (and waist-belt cinching, and pretty dress layering), you know?

If anyone's going to manage to keep the grunge look feminine, it's master of pretty, Valentino, and this printed tulle dress, £585 at Net-a-Porter, proves it. All that frothy sheer fabric and delicate lace is to the plaid underlay what the Nirvana song All Apologies is to the rest of the album it lives on, In Utero: a pure moment of calm and clarity against a dark and raucous background.
