I ♥ American Vogue's Preetma Singh in a big way.
Ex-lawyer, now Fashion Editorial Assistant at Vogue.....and wearer of her old Princeton University sweatshirt 'cos she was cold and needed something to keep her warm. Genius. I adore this look (so great with the crocodile-print patent leather skirt and knee high boots - elegant, faintly s*xy and sporty all at once) and it works even if you don't have an Ivy League sweatshirt like Preetma's. Got an old school or college sweatshirt lurking at the back of your wardrobe*? Pull it out and try teaming it with a leather pencil skirt (I think it would work quite well with a flippy leather skirt as well).
