Personally, I'm one of THOSE girls, who doesn't wear make up, AT ALL (unless forced too for like a wedding or something) who barely wears any girly clothes (I tend to wear my brothers shirts and even pants sometimes, although I will wear a skirt, albeit a long one, when it's exceptionally hot out) and who doesn't spend much time prettying up. I mean, even today, my dad came home and was like, ok girls, and boy, (my sister, my twin brother and myself) we're gonna go out, get some paper, and get lunch. What I did was just put on a bra, one of my brother's T-shirts, and pants, tied my hair up in a pony tail, and waited with my brother in the living room for my dad, and my 15 year old SISTER who took FOREVER to get ready (was probably putting on make up and/or deciding what to wear).
I think the only part of my body I actually spend time and effort to make look good, if at all, is my hair. But even then, it's usually either just brushing it, straightening it, or just plain blow drying it. I mean, given that I am not very busty, not very curvy, have a pretty deep voice for a girl, stand 5' 8" tall, and look almost identical to my twin-brother, I think I'd look more like a cross dresser than a real girl if I TRIED to look like the girls onthe street. Don't get me wrong, I'll wear a pretty dress, and TRY to look girly SOMETIMES, but I tend not to really care much, mostly because who am I TRYING to impress, I don't go out much, and if I do, it's to see friends, hang out with my brother, or take a walk. I don't go clubbing, or try to find a guy who would go out with me.
