So here's my pretty much for sure cosplay list for Anime Vegas:
Day 1: Ariel from Disney's Little Mermaid (Kiss the Girl/Town Dress Version) and Moka Akashiya from Rosario + Vampire
Day 2: Sailor Moon from Sailor Moon R (will have my friend as Venus with me) and maybe Mio Akiyama from K-on
Day 3: Decora
Moka and Mio may end up getting switched days, but I'll be wearing them both.
