I made everything! ^^ I bought a white hat at walmart, and used fabric paint for the front of the hat. Painted some white material with the fabric paint and cut out the shape of the pokeball design. The boots I found at a thrift store, shoelaces on amazon.com, and I bought the arm warmers at Sports Authority and used material that I painted with fabric paint for the pink stripe.
I have got to ask, where did you get the black vest (seems like a vest to me) and shoulder bag? I've searched high and low online and found nothing. I must cosplay Touko for one of the Pokemon Black and White tours. D:
