I went to Anime Fest in NYC yesterday and the above pictures are just a sampling of those I saw cosplaying. The Fest was fun (although the commute into the city was not) but not at all geared toward professionals.
One unique and surprising feature was the manga library sponsored by AnimeNext. There was a separate room away from the exhibit hall where you could select a manga in exchange for your badge. I spent a half hour reading Death Note volume 1.
There were several vendors but the discounts were minimal so I went home empty handed. The best vendors were those selling artbooks and other imports from Japan. I did pick up some cards, the most interesting being Squishables! They are so nice to HUG that I will definitely get one soon.
