Girls, Is there there a way to Compliment a stranger on her looks without without coming across as creepy?

Is it flattering Or creepy to say something along the lines of pardon me, I don't mean to bother you but you're absolutely gorgeous. Or Is everything that I say filtered through Whether or not she finds him attractive? If she likes you it's charming/flattering, if not she finds it creepy and uncomfortable?
