Its summer so Short shorts. I like white ones but jean short shorts are hot too. Wear flip flops or maybe sandals. In the winter, tights and yoga pants. Shows off your ass. Blots for footwear. Sucks that you have to wear a polo though.
Tight clothing is the most appealing thing for a guy to see you in. Especially if you are attractive and have a nice body and if you show skin. Wear tight yoga pants so guys can check out your ass also. Good luck!
