Seriously, shut the fuck up unless you actually know what you're talking about. I'm a male cosplayer, but fucking really? One part of my newest costume (Alex Mercer, im making the sword arm) is going to take over 5 hours to make, not to mention any sewing and misc. other things I have to do.

So you're judging her based off of her worst things?

Seems totally logical.

The Rainbow Dash costume probably took her several hours as well. The wings probably took around 30min-1hr depending on how they're held on. I would wager she had to sew the fluff onto her jacket (a good 30 minutes) as well as the arm-bands (30 minutes about). The gloves/ears/goggles are probably store bought, but it looks like she took the time to color her hair, which would easily take over an hour.

Even the dragonair cosplay you posted took several hours at least. She had to make the horns the neckpiece and the tail, as well as the gloves and most likely edit the boots.

You seriously underestimate the amount of effort she puts into her costumes.

And I'm not saying every cosplayer is good if they show their tits, I objectively judge them based off of their costumes and how well they fit the character.

My judging criteria is 2/3 effort on their costume, 1/3 if they're cosplaying in body type.
