Personally, I always ask if someone is in cosplay or not. After all, I may just not know of the series! And secondly, I'm no seamstress. If they made it, maybe I can get some tips! right? No harm, no foul.
But at the same time, at least for my own shoddy cosplay this year, I was broke. I had been kicked out of two family homes [that where my own family], and jobless for a time before I started to be able to THINK about 'OH CRAP KUMORICON!' what may have been two months before the con. Quite frankly, I was going to do Sailor Uranus all three days, but much to my dispise, my costume didn't fit with out help because I have gained ze fat. Well hell. No job for a time and kicked out of two homes by Kumo; I wouldn't doubt if I gained some stress weight! So yeah, I threw Fem!France together out of my closet, because I've gone to a cosplay thing without a costume, and felt HORRIBLE. I didn't have the 100$ for a new Sailor Uranus costume, and by the time I found out it didn't fit any more, it wouldn't have come anyways.
again, I'm no seamstress. So I sadly have to buy mine.
For what I did with a College student's pay while trying to find an apartment and car and make sure my Kitty-child-Jase was taken care of... I think I did alright. Perfect? HELL NO, but that's my own words for me.
No one knows what people go though, so if you don't like it, just don't say nothin'. Really as easy as that. But if you feel like you HAVE to say something, at least have the guts to tell the person yourself. don't be callin' people crap behind their backs, it just makes you look bad and cowardly.
But then again, what am I saying? I go for the fun and my friends and family I meet at Cons. Not just for the costumes, and most know I don't go for many of the panels either. -shrugs-
