Costume Castle is a little store off the 5 freeway at the El Toro exit. As expected, Halloween is the time when this store is the busiest, and the emptiest. If you plan on buying costumes from here, I would strongly recommend that you go there well before Halloween or you won't find the right costume and size for you. I went the day before Halloween and I found exactly what I was looking for + it was my size. I can't say everyone will get lucky but considering how small this store is, the supply is limited.
