I wouldn't put much thought into this. Many women would still act receptively to fat, balding, 50 year olds complimenting them. Of course they would be creeped out, but they won't say anything about it to that person's face most of the time. I'm speaking from experience, having female coworkers in food service who sometimes tell me when a customer creeped them out.
As long as you don't have creepy intentions, you shouldn't worry, I think.
