had to go looking around because i know nothing about body sizes that tall so take what i say with a grain of salt but maybe like 125ish?
Probably 100lbs would be good for you. Maybe 105.
I'm 6'1" or 184.5cm (yes, I'm very tall. and I'm also a girl.)
Aesthetic: thin, slim, very skinny but not unhealthy and not dangerous low. Bones showing slightly, but not unhealthy. Nice slim waist. Skinny legs, child-like, not many curves. Sort of athletic but not a lot of muscle. Waif-like, etheral, petite
and this is probably the 5th time I've posted here, but i get skipped a lot and people ignore me
5'2 94 lbs (i'm on my phone can't remember if we were supposed to put weight but saw someone do it so)
Goal aesthetic: disturbingly thin and bony, childlike/unreal
