Get rid of fat, but not too muscular and bulky?

hey, i'm a guy, and i'm not too fat, and im not too short either..

I wanted to know how i could look slim, and have like VERY lean muscles like not bulky, but not too flat either so i dont look like some unhealthy guy..

so like members of DBSK or like thos k-pop idols..

like exercises or workouts that would help me do that..
also foods that could help me reach my goal...

i also wanted to know what kinda cloths would help me to look taller, especially longer legs (since i heard height is genetics..)

THANK YOU SO MUCH
