??Back 2 School Question?

I'm a 13 yr. old girl, going into the 8th grade and I've already gotten all the materials on my school supply list. (All the way from student planner to pencils) , well i wanted to also buy a new style for myself. So whats the best backpack brand, fashion, or style (messenger bag, Shoulder-strap, sling bag, Satchel bag.) Whats the best Shoe products for school. I wanna buy these bit**in' Jordan's but my friends don't recommend them for school. What kind of uniform T-shirts should i get? (which brand because all the colors have to be navy blue, white, and khaki.) What kind of pants should i get? (no skirts. :[ not my style.) optional question: What kind of Gym clothes? Thanks :]!
