Cat Asked: how to get longer and slimmer legs like kendall jenner?

ok, im 14, not too fat, not too thin. im about 5'5 and size 8/10 uk dress size. and i just love the kardashians but the best body type for me is kendall's. i would just love to know how to get legs like hers. please don't tell me about genes or my diet. i know. i just want some exercise tips (lots) and some info about when i'll stop growing, i read that you stop growing around 14/15 but sometimes into your twenties- i really want to know an almost exact time, my dad is almost 6ft and my mom is my height. once again yes i know kendall's thin because of her genes and i know about my diet- im very healthy. but it's a shame because in my school we only do p.e. once a week (idiots i hate them). and for only 30 mins- between changing, instructions blah blah blah. so i'd like some tips about exercise, stretching etc and the science behind my height lol. please no stupid or mean answers, don't post garbage because you have nothing better to do with your pathetic life, any HELPFUL answers are really appreciated and i will give ten points to the one with the most information. again, thank you so much, i really need help!!!
