I've been treating myself to a new wardrobe as time allows. I've bought several new pairs of pants (making sure they don't give me any room to gain weight!).
Don't forget your undergarments! I've been trying one and buying bras but I have to make sure I've found the one I love most before I replace my entire collection. I'm also going to replace all my underwear, but unfortunately I'm between-sizes in my favorite make (and I don't plan on losing more).
