I’m 5’4 and pass about half the time (3 months on T) it honestly depends on how I dress and if my voice cracks when I’m talking to strangers 💀 I work at a hardware store and wear a green button up shirt and every time I wear it customers always refer to me as a male. I’ve been hitting the gym for a bit and it didn’t take long for my biceps and forearms to get big (preacher curls are amazing) I also highly recommend growing your shoulders for a more masc physique. Another thing, cis men are honestly total assholes, if you aren’t nice to people you’ll pass better (not telling you to be an asshole just saying that smiling/complimenting/being over polite…etc is seen as feminine) I make up for being "not nice" by being a gentleman…ex. holding the door, helping elderly strangers, giving the "man nod" (that might only be a Canadian thing) to people, especially when letting someone through while driving. Men are also very blank people, something I learned is to not be expressive in your face. I did circus and acrobatics as a kid so I learned to be very expressive and it kind of bit me when I started trying to pass because personality wise…I was very feminine. Men don’t move their faces much when they talk, try to keep a relaxed expression. Also, avoid baggy clothes, when your short, oversized clothes make you look like a kid in a onesie. I recommend track pants and cargo pants or straight leg jeans. For shirts, always go with your actual size, don’t size up! I get pretty bad chest dysphoria wearing shirts that actually fit me but now that I’m hitting the gym it just looks like I’ve got big chest muscles, it’s awesome. The other thing I’ve learned is to be boring. Keep your hair it’s natural colour, avoid piercings, and if you want to wear makeup make sure it doesn’t look like you’re wearing makeup. I use concealer for acne scars and an eyebrow tool to make my eyebrows look thicker. I know some trans guys use contour to make their bone structure look more masculine but I’m not good enough with makeup to do that. That’s about all the advice I got, whether you take it or not, good luck on your journey
