Short skirts or shorts is most comfortable dress code for playing tennis. Women wear skirts and men wear shorts.. thats the usual norm. For people who say Sania can play in long shorts like Sampras and Co.. How about you guys wearing quilt.. not even long skirt! doesn't sound good right! So better keep your personal choices to yourself! Do not make religion a issue! If you want to be a religious fanatic, you better live in other suitable religious countries(Do not come back to India because they will say you are still too advanced for them)
