Congrats! I love finding out I'm 'smaller' than I realize, it's a fantastic feeling. This past year I've gone from a 24 to 14. Thankfully I saved a lot of my clothes so I had plenty of things to wear until about a size 16/18. Of course now all of my 'small' clothes are too big. I'm in that weird place where I'm still 60lbs from my goal so it doesn't make sense to buy a lot of new stuff. I've been buying gently used clothes at thrift stores and ebay. As long as you don't bind buying used, you can get a whole lot of clothes for just a few dollars. If you want new stuff, stores like TJ Maxx, Wal-Mart, ... are great for inexpensive items. I'd suggest buying a few basics (jeans, black pants) that can be worn with many outfits, and then when you're closer to your goal you can get better stuff.
