Where can i find Authentic Historical costumes?

Question

I'm really big on history and for Halloween i would like to be something historical (i.e. Roman Legion, Aztec Priest, WW2 soldier, 20s mobster, etc...)

Where could i find Authentic Outfits that do not look fake but real or even close to real? I would like to be an aztec priest this Halloween? where could i find a complete outfit or where could i get the clothes/materials to make it?(if not aztec then anything else historical is fine)

You can list sites, or store locations around the New York City/ southwestern part of Connecticut, USA
