Who is she posting these for? If it is to show off her costumes, then I guess they are decent from that perspective. This hardly seems the place to give the sets their proper audience, though, as the previous poster's tone suggests.
I mean....95% of the cosplay galleries don't either. She's cute enough to not deserve the downvotes when you have fugly cosplayers getting upvoted just because they flashed their panties briefly in a single photo. She's also not the one posting her galleries here, so the better question would be why is the poster doing so?
