Well I plan to cosplay as Matt and L for Sakuracon in the spring and I can ONLY find the shoes, goggles, and stuff! xD
I found the a good shirt (The ACTUAL colors. (Red and Black)), and some okay goggles, and awesome boots, at http://www.findcoolclothes.com
at Slash N' Burn.
you're also free to email me (email@example.com) or IM me on Yahoo. (ivy_like_cows)
HOPE THAT HELPS!
