I have no body shape?

Everyone says i have just the right amount ( tiny dip in waist, tiny curvy legs, etc) but honestly i think they're bsing me lol. I'm 15 ( about to be 16) i still wear an A size bra, i feel like i have a square torso and whenever i do gain a little weight the first place it shows is in my stomach ( i weigh 110 i think? it reads 105 but think you have to add something lol i dunno) But yeah, i feel like my body is so boring and disproportionate due to my small :( ( which i hate) Anything to enhance this? ( Don't say gain weight, i am a recovering anorexic girl..so please don't.
