oh i heard about a surgery for narrower shoulders. its called clavicle shortening. theres a limit to what they can do, i forget how much, but its cool that its possible. not sure id get that one personally.
ive thought about getting the ribcage remodeling but neither method seems great to me, either the rib removal (potentially serious breathing issues) or the breaking method (requires a corset for months and might just go back to normal after). maybe after another year or two of hormones to see what i get.
