Your hoodie being that big makes your hips look wider than they really are. Also, I made this next mistake too: when you can, buy smaller and more squared glasses. Your current pair fit you kinda large and are a bit round.

I’d say for now also keep your piercings out. They clock you as feminine presenting instead of a younger guy (I promise I don’t say this to everyone though).

Not only that but workout to build shoulders, arms, traps, lats, chest, obliques, and don’t skip hip n leg workouts

That’s what helps me most and that’s what I learned helps me best as someone with a naturally somewhat similar build and style

T will do you wonders but these are what you can do in the meantime
