Real world me:
MtF transsexual, lesbian.
6'1". Way skinny. Shoulders far broader than I ever desired, and hips? What hips?

At this point in time a 34/almost-A.
Hair length getting nearer to the base of my neck.
My fantasy me, purely hypothetical, since we're on the topic... (cue soft focus)
Cisgender female, still lesbian

Long silver hair to the bottom of my shoulder-blades.
Yes I said silver. I have a thing for gray hair, lol.Something like 5'6"-5'8". More curves but slender is fine. Shoulders equal with hips, and gimme some hips!
Same eyes (blue). Smaller jaw, and definitely a nose smaller that this schnoz I have now.
Maybe a lighter skin tone, but that doesn't bother me too much.
Never desired a large chest, something like a B would be nice

(end fantasy...
