My 15.6yo DD is stunning, tall ( 5'7" and growing) size 6-8 depending on where she shops, lean and lithe (gymnastics) the most amazing hair and lovely teeth ( braces at the moment but they'll come off next year).
She is at the age where she doesn't recognise just howgood she looks though, and wishes she had hair like her BF (sleek almost jet black) whereas BF would like DD hair ( light brown with body) 
I notice that she does get a lot of second glances, comments, one bloke blatently asked for her phone number. Mostly they're late teens ( I have an 18yo DS too so I think how he would do a double take look at an attractive young woman) or the double looks from other girls ( I know I will look twice at a woman who is dressed well, has that aura about her etc)
Course DD wears make-up (loads) but in a no make-up make-up look, has ears/cartilidge piercings and sometimes we clash over clothes (but she's pretty laid back, most of the glances she gets , she's in jeans and converse). Usually its "You cannot walk in those shoes" and I'm always right on that one !
DS is stunning ( yes Mothers Biased Opinion here ) tall , angular face, very long limbed and thin, with gorgeous teeth, hair, beard . But his clothes are basically what falls out of the wardrobe , unlike DD.
