If I could change anything, I would change my feet and boobs,but not because they look awful, but because they are difficult to fit and consequently expensive, with less choice. Oh and hair that behaved itself! But no grey hairs yet (well between you and me, some downstairs!) and still blonde.
I'm 61 and look a lot younger and am a better shape than since my early teens, so that clothes do look better. DH does compliment me on the way I look, which helps my confidence. I don't worry about the way I look as much as when I was younger. I look at old photos and wonder what I was fussing about.
I look at other people and find I am attracted to who people are rather than what they look like. The beauty within shines through.
I do wear makeup when I go out as apparently I don't look very well without it, regardless of how I really am! I am naturally very pale.
