And another thing that irks me is people using the "your the wrong race for that cosplay" thing. using that logic, no-one should cosplay cause, esstentially, they're cartoons and no-one is a cartoon.
I find that really annoying, especially since some people expect "decent" cosplayers to look exactly like a character..... when really, that's going to be impossible. I was actually really surprised when I cosplayed as Lavi, since he's, what, 5'10", and I was (and still am) 5'2", and yet no-one commented on this, though that may just have been because D.Gray-Man wasn't all that popular several years back, or at least not on the scale that it is today. Cosplaying is, after all, about dressing up and having fun as a character that you love, no matter what your race is, or what race they are. That's one of the things that makes it so different from theatre, where sometimes you need to have specific physical features to get a role.
Onto the harsh comments, I haven't really received any that have stuck in my mind, which I suppose I'm grateful for. But some people I've been with have, which really annoys me, especially when it's people I've only just met at an event, and someone immediately compares us or maybe says something without thinking (eg Allen shouldn't be taller than Lavi/why don't you have his gloves, you suck/couldn't I just have a picture of this person). The first two are simple to answer *points above*, since it's only that person's interpretation of a character, they may not like wearing gloves, or not think it suits the character so they dropped them. Also, it could be a simple case of forgetting to pack that certain item. It's happened quite a bit to people I know, and sometimes others don't realise that the reason they aren't wearing an accessory is because they forgot it or lost it.
The third example is rather annoying, though I can see why people do it. They're not meaning to be harsh or anything by it, but by not wanting a photo of you/your friends too, they're implying that your costume isn't good enough. It may just be because they don't know the other characters in the group and just want a single shot of one specific person, but it's still nice to take a quick pic of other people in the group to make them feel included.
My friends are really supportive of my costumes the majority of the time, since they all love anime to pieces too (and somehow can put up with my random ramblings), and have taken a liking to giving me short characters >< But 'tis all good, everyone likes to make fun of Ed Elric every once in a while.
My parents I think are on the fence about it. They think it's good and all, and that I'm learning really good skills with my sewing and comment frequently on how much I've improved when I actually get round to making something, but don't like me going to so many conventions (just the London MCM's). I mean, they're starting to question the whole point of it, but cosplay has allowed me to see my talents and my failings, and work on them, as well as point me towards what I want to do in the future (theatre work). Part of it may be that they don't like having to drive me up/stay in a hotel for a weekend at a con, but they've also stated that they're not sure about the kind of people who go to cons..... even when I'm saying most of the time that everyone is really friendly and it's a really nice event. And whichever hobby you choose, you're always going to meet bad eggs or people who are just there to cause trouble, and my response to that is if you're not so sure about the people who like anime, then what about the people who watch Doctor Who? There's going to be a massive range of people who are fans of either of those things, and if you went to a show dedicated to a different type of TV program, not much is going to change. Just because they like anime, doesn't make them a good or bad person :/
Anyway, I congratulate anyone who got through that massive wall of text and managed to understand most of it xD
