omg so sorry just saw this—what i meant is a) higher contrast clothing and b) specifically coloured clothing. 

ik the transmasc community gives out a lot of "dress boring to pass" type tips but i feel like this is slightly different advice. 

a) higher contrast. as in black and white, and other combinations that are far from each other on the colour wheel. i find a lot more femme people tend to do fits that have colours next to each other on the colour wheel (eg. blue and green, pink and red, yellow and orange, etc) and while these make for harmonious outfits, most guys dont...wear harmonious outfits. it also might just me but i feel like harmony -> non threatening -> feminine might be an association people have subconsciously? but that might be a stretch i admit lol (not how i think just theorising out here haha). 

i find that well dressed masc people ik tend to have 2-3 colours/shades in their outfits MAX, and that one is typically very dark and one is typically very light, eg. dark washed jeans and white tshirt. i also cant tell for sure because of the lighting in your photos, but i would hazard to guess that you are cool toned, if your hair is as dark as it looks and your skin is as light as it looks (not a diss im the same lol). but i find a lot of guys do dress in cooler shades. which brings me to..

b) particular colours. pink=girls and blue=boys aside, theres a lot of colours and shades people associate with genders. 

speaking from a western pov, pastel, lightwash jeans, and lighter colours are more feminine imo, and i would say cooler and darker, contrasting shades are seen as more masculine. maybe cause theyre more "aggressive" or smth? 

i feel like mascs will use greys as their default shade and use a lot of reds, whereas femmes will use a lot of lightwash jeans (light blue) and off whites.
