How to kiss a girl your not dating?

hey, i am going to the movies/mall on sat with a couple of friends, one of them i like. I had my female friend ask her if she would hu with me, nd she said prob, im wondering if i should try it in the movies with the group or just not try it at all. Also what should i wear, decent aeropostale jeans with a nice black shirt w/ silver writing, or our lax teams shorts nd shirt? nd how much cologne should i wear, enough to barely smell it or more? sorry for so many ?'s just curious
