OT: Office Ettiquette... How do I politely tell a young lady that I'm allergic to her Perfume ?

I've had to do this a hundred times. Just blurt it out to her and then try to joke about it. There's a 95% chance it will go well. If it doesn't, you'll just have to write her off as a jerk.

I was test-driving a car once and had to ask the salesman to go back to the lot NOW, it was so bad. He apologized and said he was taking chemotherapy and had lost his smell.
