Women in my family have decently large breasts, and I would say my breasts are small for my frame (I couldn't fill an A-cup in my band size, for example), but large enough that other transfems in my life have expressed jealousy, and I get men staring at my breasts sometimes - so ... I think this tracks the typical wisdom I hear that you will usually be a size or two down from the typical size in your family.
The difference between my band size and my bust size is 7 inches (17.8 cm), which technically means I have DDDD / G sized breasts, but that's using the mainstream cup sizing chart, which assumes an average band size around 34 inches (86.3 cm):
https://en.wikipedia.org/wiki/Bra_size#Cup_measurement_methods
In reality, for my actual band size, I struggle to fill even an A cup. It's my damn rib-cage, which is very wide and makes me barrel-chested.
in order from what we most enjoy to least enjoy genetically, body-wise:
- legs develop muscle like it's nothing, and fat goes there too with ease
- very big, uh, rear end
- quick breast development
- didn't start HRT super long ago, but breast development was noticed like literally two weeks after starting
- family has VERY large breasts, to the point size reduction surgery was needed to relieve back pain for an aunt
- also a bra is a must for us. bike rides without them are uh interesting to say the least (currently C cup size per a chart, more so B in reality)
- femme looking face/eyelashes/jawline
- we passed before starting HRT, but still helpful!!
- long legs compared to torso
- women's tops still fit us well despite our height, plus sexyyy
- thigh highs are hard though
- voice wasn't super deep, not exactly high pitch albeit certainly above average
- has been very helpful in achieving a passing voice
- pretty tall stature
- body metabolizes nutrients insanely quickly
- estradiol has helped a little, but not too much
- has led to very low body weight (this can be bad!!!!!)
- fairly large feet
- SO much body hair to contend with
- hormone therapy has helped a crazy amount, making hairs whiter, thinner, and grow slower thankfully
- on HRT, our body can BARELY regulate temperature
- our sister actually has to take a medication for this.
- skin was eating itself alive, estradiol solved that though
also i have similar feet of dad sister her is 39-40 EU, my shoe size 40-41 EU mine larger due flat feet but not androgen expouse, my dad is ~43 also on hrt feet became feminine and smaller old shoes sits too freeit was 41 EU ALSO it changed the angle in x ray now it more "healthy" my mom shoe size is 36 EU (is too small for 160 cm.... often she hard to find right shoe because is more child) interesting but all my female relatives ~160 cm height dad is 177 cm
dad sister really have unhealthy weight we are similar height and im also same pre hrt, pre psych pills now im ok face shape is something similar to dad side female relatives
my mom didnt have body hair at all until hormonal disbalance high DHT, 2 nmol T and im doesnt have at all even after super high T and DHT
