crossdressing

so i jus saw another post abt it and i thought of something that always confused me. why is crossdressing even a problem in the first place? girls wear all types of clothes including suits, sweat, joggers, etc. and it's not called crossdressing. for fucks sake if a girl wore a suit she'll be called a boss lady or sumn, but when guys wear dresses and the like why do people get mad?? why do certain cuts of clothing become associated with gender in the first place- idk human logic is so flawed, i wanna commit unalive bc of it sometimes...
