i dress younger than my age (late 30s), mostly plain stuff in muted colors due to me being pale as fuck. Black or grey jeans, light grey hoodie, shirt for appointments, sneakers, functional jacket or coat.
/fa/ helped me to develop a sense for what looks good (best tip: having proper fitting clothes) while also not looking too overly faggy.
It's a good cope for me but going into the shops can be a bit tedious with all the people, i prefer doing that during off hours, when the normies are in school or working
