I'm meeting a girl through a friend in a few days, and I'm fairly excited about it. Anyway, I found a really charming pickup line in an 'outrageous/hilarious pickup lines' post a while back, and my friends agree it's great, and a decent reflection of myself.

"hey, do you know what kind of material this is?     (directing attention to shirt) "I dunno.. cotton?" "No. Boyfriend material" 

Anyway, my friend told me that she is majoring in fashion design, which means I am morally obligated to use this. But where should I go, conversationally after that. I don't want to seem like I put all my effort into just the pickup line, there has to be some follow up.

I'm not bad at conversation, per se. but I'd love to see some redditliscious ideas.

EDIT (update): Well, I met her and used the line, she laughed, and I got her number. But apparently she's been chasing someone from her class and is making progress on that so... meh. Not a success, but not a fail. try again, later.
