I wear what I normally wear all the time, all this weekend when I was at clubs, I had people who I didn't know all doing shots with me, giving me respect, girls who wouldn't dance with anyone dancing with me,etc.
I have a theory that people should wear what you would love to see yourself in if you were watching a movie about yourself. My style represents my ideals and the way I view myself, my hair is the center of who I am. I try to advise people to wear exactly you love to see yourself in, and forget what other people might think.
Depends on the weather. Typically I'll wear a short dress (not super, skanky short but a little bit above my knee caps). Then I'll wear a cute pair of heels and a jacket. If you're trying to figure out what to wear to the club, please don't be the type of girl to wear jeans/barely dress up for it. You stick out, in the wrong way.
