I’m a girl who believes in a uniform. Fall? Skinny black pants or jeans, scoop neck tee, blazer or long cardigan. Winter: add a giant scarf. Party time? Same skinny pants under a dressy jacket. Really fancy? I begrudgingly trot out one of a stash of ancient party dresses. If you’ve got a closet full of classics like me, here’s an instant update to your little black dress without breaking the bank: glam earrings at $14 to $24 a pop (or stash a pair for an unexpected hostess gift). And if you haven’t gained an ounce since high school, check out Ciao Bella’s delightful inventory of sophisticated (but oh-so-short) party dresses, most under $75.
