Girls, at what age do you make the transition from regular perfume to old lady perfume?

So back in college a girl was sitting next to me in a big lecture hall class and we started flirting with each other, the more we talked the more i realized she was wearing this perfume that i could only describe the smell as something a grandma would wear in a retirement home and it turned me off immediately 🤣
