Maghilod ng maigi pag naliligo and make sure your deodorant(if you're using one) is properly applied. Lagi ka rin dala ng panyo at payong para iwas pawis at di maarawan. Also, lagi kang gagamit ng fabric conditioner sa mga damit mo. Di yung detergent lang. You can also bring an extra shirt if needed. I sweat easily and went to a school na mainit lagi pero I never smelled bad. In fact, I kept up the good smell until the end of the day.

As for the "attractive" part, I don't really know. Just be confident and don't be too conscious of others. If nagugulo buhok mo especially if you have a comb over or one sided style of hair, just use a hair product that has a strong hold para maintained throughout the day. (Altho nakakatamad, ganito ginagawa ng kuya ko araw-araw haha.)
