Wow how this thread has taken off!
I, too, struggle with body image in costuming, though in my own peculiar way. I'll admit, I have more low esteem/struggle with my face than my body. Ever being the perfectionist, if I feel I don't really look like the character, even if I act a lot like them, I won't do a costume (not that I judge anyone else for doing that! This is just my own peculiarity).
You know I feel the same way... Zoe from Firefly is one of my favorite characters and her costume(s) are soo cool. But, I'm a tall, thin blonde with thin lips and I just don't think anyone would recognize me. haha
Being what I look like and what gets written into roles of movies I liked enough with characters I like, I was kind of stuck until LOTR's came out. *heh*
There's a lot of pressure for women in costuming, to be sexy and revealing (regardless of where it comes from). I tend towards the modest/conservative side of things, so I don't like sexy costumes for the allure of being sexy.

I'll admit, I actually am getting a lot more pressure for NOT wearing revealing clothing. It's a weird phenomenon I've been observing lately. I'm an agency-represented model, so I am a tall, thin gal but I didn't realise that supposedly excluded me from wearing modest costumes for some people. I've actually had people get mad at me for not baring my midriff, chest, bum, legs, etc. I don't get it. Has anyone else experienced this?
That's an interesting observation... I'm pretty modest too, but I've never felt pressure to wear something sexy. I've been more discouraged that there are so few costumes in certain genres that aren't skin tight or baring so much.
Personally, I love armor and men's fashions more than what the costume designers come up with for the women. Sure, some of the LOTR dresses are gorgeous, and I did do Galadriel once - but the detail on the elf armor and now the dwarf's armor, it's breath-taking.
The only time I ever got any flak for a costume was when I was dressed as Haldir in Canada and was being interviewed - they wanted to know why a woman would dress as a male elf when there were female elf costumes. I was like - uh, did you see how cool this armor is? Why wouldn't I want to wear it??
An other for instance is the Avengers cosumes... All of them are really very interesting and detailed, except... you guessed it, Black widow. All she has is a boring cat suit. Now some girls can pull that off and look fantastic, but it just doesn't inspire me, even if it were more modest. *shrugs*
Guri - Yay for getting your children involved in costuming too. That automatically makes you one cool parent!

My oldest is so over costumes... I wanted so badly to make him Captain America, I love the costume, especially the older, muted, combat version... but he wants bribes to wear it. Not as fun. Thankfully the youngest is still into it and loves the same characters I did. Making him Legolas was like a dream come true. (now if he would only stop growing so he can wear it again!)
