The only piece I made was the skirt. Checkout Sparkle Pipsi's tutorial! (she also sent me the neck bow premade and sells them in her store) http://sparklepipsi.deviantart.com/art/Love-Live-Skirt-Tutorial-419016067

I have been through 3 sweaters from various places. Socks and shoes are from Famous Footwear. White dress shirt is the juniors line from French Toast. As for the wig, I started with a pre-pigtailed wig from Epic Cosplay (update: Second wig is a Nico wig from Ebay). I straightened the pigtails and reset them, higher.
