Pulling off a good Little Sister cosplay is tough! Go too far one way and you'll look creepy, go too far the other way and you'll try and look sexy and end up being even creepier. This one, though, nails it.
Taken at this year's Otakon, and snapped by photographer LJinto, they're everything that's awesome about cosplay in 2011. Good source material, good costumes, good photos, good effects.
You can see way, way more awesome cosplay shots (both of the Little Sister and other stuff) at LJinto's Flickr page, linked below.S
