Probably an I, because I'm skinny and upstanding, usually 😆

The letter 7, because I have long wind-blown hair, am reletively slim, and I have scoliosis

lowercase i

A D, I'm all tummy😁

Lowercase b. I'm thin but my belly is a little fat.

R - put that arm on the hip and stroke a pose.

s - I am like the tiny "s". You can never tell if I'm upside down and I do have two hooks but no clamps.

Same as cloud

B - big boobs/big belly
