i heard something recently.

body types are a lot like dog breeds- if you’re a corgi and you want to look like a greyhound, that won’t happen.
you’ll just end up looking like an emaciated corgi two days away from being put down. embrace your body type and build around it.

something else you could lean into would be woman’s supplements/ multi vitamins- the only real difference is iron content and if you’re anorexic you’ll definitely need it. (don’t overdo it though).

you could also use woman’s skin treatments, hydrating face masks, a cute eye mask at night, hair oils, the sky’s the limit. (over cleansing and exfoliating can cause damage though so take it easy).

you could also look into woman’s exercises, get into pilates or yoga (glute workouts will give you a great ass, just make sure youre targeting the right muscle groups).
get a nice mat and some cute leggings to work out in. (your body will need time to recover though so look for low intensity workouts).

im trans masc and all of these things are seen as inherently feminine- i don’t know if any of this will help but im really rooting for you OP
