Group date thing tonight!!?

I'm going with a group of people and a new guy to a play tonight. I'm wearing a grey/navy blue cardigan, jeans and flats. I'm gonna wear my hair scrunched, but I don't know what to wear for makeup. I have light blue eyes, and I have the eye enhancer stuff thats navy blue, I could use that on top as eyeliner and saphire/black mascara, or something else entriely. Also, should I do a light fruity scent, or a more seductive scent, thats still pretty? Thanks! Any help/tips are appreciated. :)
