So what's your opinion? If you were wearing lolita a convention and someone came up to you asking for a picture would you be ok with this and politely accept or refuse, or just consider this rude?
Personally I don't have an issue with having my picture taken, I've been to a few conventions both in and out of lolita, and have been asked for my picture at least once each time (which admittedly really baffles me sometimes, especially when I was walking around in a petti and T-shirt xD). I've pretty much come to accept this as part of the convention culture, and in the same way I have gone up to people to ask for pictures and they seem to consider this the norm for the most part as well. However I can see how this could make some very uncomfortable.
I will say that I do think it's a bit out of line to take pictures without permission. And of course it's very rude to insist for a picture even after someone has said "no".
For the record, I have no opinion of "right" or "wrong" in this situation; and I'd like to clarify by saying that I'm not asking "Do you think it's ok to refuse having your picture taken?" because that's your right, and it is never wrong for you to refuse a picture for any reason.
