Congrats! You'll have a GREAT collection in no time! I agree with krispin41, don't ever let what others say "get" to you! My daughter is 10 and I've been trying to get her to get a cute Coach bag but she hasn't found anything she likes!
Congrats on your SUPER cute purchase. I think it's wonderful you have such an appreciation of nice things at your age. I wish I had a teenage daughter - I have 2 teenage boys and it's always fun to see what bags the girls they hang out with have. You Mom has given you very good taste!!! Enjoy your new purchase!
