How to dress more masc without it looking shitty?

Yea. I find it really hard to find clothes that i like. A bit of context: Im a trans guy and im not rotting in toxic masculinity, but i wanna pass. Also in my area girls are often more open with expressing themselves through clothes and i sometimes find myself wanting something, but don't buy it because its more often worn by girls. Guys are dressing usually like NPCs and/or wear sportswear while not doing any sportsy activites at all and skipping PE lessons at school. Maybe thats a bit too much, but I value symbolism??? in what i wear. For example I wouldn't choose a tshirt with a huge expensive sportwear brand logo on it because im a computer nerd who rarely touches grass. Sometimes im even considering making my own tshirt (maybe even sew it myself), but i can't come up with design that i'd consider perfect enough. 

Sorry for the yap. Help me pls🙏🙏🙏
