Night Safari

Im going Night Safari tomorrow & I basically have no idea what to wear. My friend, Nasiha, suggested me to wear plain simple like a t-shirt & jeans since it's only going for Night Safari outing. My other friend, Rohana, suggested to wear a knee length skirt with t-shirt. With these suggestions I still have no idea what to wear! Tomorrow, I got to work & this will even make me more worse. The moment I reached home I got to quickly get ready since by the time I reached home it's kinda late with my time donning myself will be time consuming. What can I say GIRLS! Eeeee! What to wear???
