Just remembered this website, it is PERFECT for this project, for the whole recycling of clothing etc etc...
Big Wardobe - you set up an account (for freeee) and take photos of clothes you don't want/don't fit/don't like or whatever reason want to get rid of, and upload them (for freeee) and then browse for whatever clothes you do want - any particular brand, make, if you want a blue skirt or pink shoes, just search it, and when you find some you like, people will have listed it as either a SWAP or CASH orrr BOTH in which case you could obviously do either - buy something outright (CASH) or swap it for one of your listed items! All this for freeee! :)
I love this website and you can find such good stuff on there!
