Sounds like you are ready, willing, and able for a bit of a style change. You're in the right place! Have you read any of Angie's blog posts on dressing the different body types? If you would like help figuring out your body type you can post a picture of yourself in clothing that shows your shape, with arms down to the sides. You can block out your face if you prefer.
If you prefer to not post a picture, you can look through the archives of Angie's blogs for tips on what to wear. You can learn so much here about where to shop and what brands work best for particular types. Some manufaturers make clothing for curvier figures, while other manufacturers make clothing for straighter body types.
