Fitted, hip-length sweater + denim skirt (A-lines are fresh right now!) + knee high boots = casually chic. Add a large pendant or other piece of statement jewelry, or a scarf for added interest.
Boots from Avenue - stretchy to fit your calves, a little heel for height and sex-appeal.
Basic, 9-5 suit in the color of your choice + lacy camisole + glittery clutch + strappy heels = party perfect. Ditch the little black dress in favor of something a little more unexpected...and warmer!
Hit the lingerie section to find a sexy corset to pair with your suit. Don't worry - your suit jacket will cover you up a little!
Black top + black skirt + opaque black tights + brightly colored shoes (think red, yellow, blue, pink) = punch of fun!
