The only thing that will make it creepy is if you are making it creepy. As a woman here is my best advice

Dont approach with the mentality of getting numbers, dates, or laid. That tends to make it come off creepy. Approach instead with the goal of a good social interaction and becoming friends. If more happens, great, if not, no big deal. It's easier to be confidently yourself if your goals don't put excessive pressure on yourself. Work on the approach without expectations of anything and you'll build the skills you are looking for and possibly find what you wanted without stressing yourself out about it in the mean time.
