Sweat pants to wear to school but still look nice?

okaaay so i have really skinny legs but i love weaaring sweat pants but i only get to wear them at home because i think they never look nice on my legs because sweat pants that look normal on other girls look reaaaaaallly baggy on me. So what kind of sweat pants should i wear; brands of sweatpants, the ones with elastic on the ends, just straight down sweat pants. THAAANKYOUUU(:
