Another technique that you could use to build some anticipation, and make your intentions more clear at the same time
'Come looking good girl, I'm gonna save a dance for you'
'1st drink on me'
You can always play the facilitator role all the way out - taking her hand and introducing her to a few of "your" folks. They only add to your cool status. In a scene where 'nobody knows everyone but then again they know of others' you are the quasi host. In a unfamiliar setting folks will gravitate back to those they are the most familiar with. Comfort/familiarity works in your favor.
