Weird press: funny hip??

Okay Im really conscious of the shape of my body. Im very slender and dont enjoy a very curvy body (which Iv other hated) but instead of both my hips being curved I hold one hip that is curved and the other hip go straight down. Its like I haven't fully developed but Im 19 and find it extraordinary that its only one hip!! dont suppose anyone have the same problem or know what it is lol?? Try some characteristics of exercise to build up the straight side.
never heard of that one-maybe u slept on one side more than the other one lol
