Maid Marion's advice is great, I think. Maybe find something which you like but is right at the edge of what you're comfortable with and wear it around the house for a while. I bet after a few days or weeks you'll feel completely natural in it. And then something else, which maybe would have been "too much" for you before, will take the place as being just on the edge of your comfort level. At least that's worked for me, taking baby steps and trying to be (mostly) comfortable at each step. After a while you can shift more than you'd believe!
