If girls are comming up to you and complementing you, you don't need an opener--they just opened you. It seems like you have a natural transition/real time constraint/DHV simply in saying where you are going, if you present the audition and passion for what you do in that way. Otherwise, I really don't think that a suit is a liability. I usually sarge wearing a blazer (admittedly dressed down with a T-Shirt), but it makes you stand apart in a good way. Just go about things the same way as if you were wearing a T-Shirt or anything else. The suit will just set you apart from the rest of the guys in some contexts, and as long as you have a playful attitude, it shouldn't change much in terms of how you approach.
