What do you do when you receive a box of hideous clothes for your child as a gift?

My mother in law has made it her purpose in life to continually send our 1 year old daughter clothes. This wouldn't be a bad thing if it wasn't for the clothes being extremely frilly, little-house on-the-prairie-style, impractical and completely out of sync with my tastes. She buys most of them at an overpriced boutique in the midwest where she lives and it's impossible for me to take them back. I don't know how to get out of NOT putting my daughter in these clothes and finding a new home for them. My mother in law is coming out this week and I'm sure she is going to expect to see some of the outfits on her. ARGH!!
