I've been living as a male now for just over 10 years, no T, no surgery, and i'd say i have a pretty good pass rate (I rarely get read which aint bad considering i'm only 160cm (5'3) and 50Kg (8st) not a big build
Best tips i can give is to wear loose but not too baggy clothes (I've found that if top clothing is too baggy it will tend to blow and cling in a bad way if its windy) but a loose reasonable fit seems to avoid this. Bottom half totally avoid stuff like boot cut jeans, even the mens ones seem to emphasise hips and stuff, go straight cut regular fit all the way. Horisontal stripe/s top half make you appear broader in the shoulders (minimising hips) and also for some reason wearing a lighter colour top than pants seems to have a similar effect. Patterns/logos on the front of T-shirts seem to take eyes away from bumps, which also helps.
Body language, basically, take up as much space as you can, when you sit somewhere, spread out, for some reason girls seem to take as little space as possible, men are the opposite from what i've observed, it also feels more comfy to me to spread a lil.
If you have the confidence, make eye contact with people when you walk down the street, I've found that if you look people in the eye, they do one of 2 things, they look away or look you back in the eye(if they make eye contact, just smile, mebbe say g'mornin or somethin). Either way, they're not looking at your chest or body shape. For me this took a lot of practice as I wasn't a confident person, but the results are awesome as I'd say 95% of people will look away rather than make eye contact anyway (in my experience).
Physique wise its tough, as the last place fat goes from is the bum and hips, so losing pear shape is very hard unless you can reach the bottom end of your ideal weight for your height, and the do a bit of weight training to tone up the top half a bit. If you can build up the arms and shoulders a bit it makes the chest look more in proportion, doesn't have to be a lot tho
( I once tried to bulk up my top half by weight training and geting my weight up to 9st7lbs, and was totally gutted to find it all landed on my hips not my shulders, which is why I recon staying at the bottom end of your ideal weight is the best unless your on T)
I guess the guys who are on T can give better advice for those who have a more manly shape than me tho
anyway hope this helps someone
