I read some of the original thread and I do find this so interesting - trying to untangle my own feelings on this and reading how others feel.
So much collective time and energy is wasted due to the pressures to "perform" femininity, and discomfort/pain endured - from the rags and rollers my grandmothers wore to bed, to the normalisation of plastic surgery today.
(I do see this being gradually extended to men now too, as making people feel they aren't good enough is such a great marketing tool! but enough about teh menz.)
I'd agree that removal of body hair, makeup and the elaborate colouring and dressing of hair are entirely unnecessary. However my dad is a bit of a dandy and I cannot shake off a belief that cleanliness and a certain level of neatness are essential. He would never leave the house unless he had washed, cleaned his teeth and combed his hair, and he's passed that on to me. My mum rarely wore makeup when I was a child and didn't colour or spend lots of time styling her hair, but she too was always clean, if not quite as anal about some of the details of grooming as me or my dad (mum will wear sandals with chipped old nail varnish, dry skin on show - I NEVER would, I just wouldn't! Mind you she wouldn't wear a skirt with hairy legs, but I would.)
I notice things like nails - often I meet people who are beautifully dressed, hair styled and made up to perfection, but they have dirty nails or shoes that haven't been heeled. I am rarely beautifully dressed and I have "Irish" hair but I would be mortified if I had dirty nails and wouldn't wear a pair of shoes that needed cobbling.
My body hair is fair and fine textured so perhaps that is why I have never felt obliged to remove it, though from the age of about 12 I have enjoyed stroking my newly shaved/waxed legs. I feel quite sexy with underarm hair, I think that's because I associate it with being intellectual and European! Bikini area, well I did used to get Brazilian waxes and I found the lack of hair underneath very comfortable, especially during my periods (am a mooncup devotee and the combination of using the cup and having very little pubic hair made periods much less of a trial) but after the first time I asked for the front to be left alone, I felt less feminine without the "triangle".
I love makeup, clothes and experimenting with hair, but I usually just brush my hair and clip it out of my eyes and wear jeans and a top with flat shoes or ugg boots. I wear mascara most days but I certainly don't mind being seen without it. For work I wear more makeup (mascara, kohl, powder, blush, tinted lip balm) and take more care with my hair, but we are expected to look "smart". Also I have always looked young for my age and feel that makeup makes me look a bit more mature.
I can't believe I've rambled on for so long and not got to the weight thing yet! jayzus.
If anybody wants to critique my thinking on this please feel free, I only have a couple of friends who are feminists and don't often get to discuss this stuff.
