Yes, I think it is most definitely Unisex and I believe the EdT is less floral than the EdP. If I were you, I'd try both. Someone mentioned on the men's forum that it is an abstract perfume, and I agree that it is. I always thought of No.19 as representative of Coco Chanel's masculine side, but that is just my impression. Another that is worth trying by a man or woman is Cristalle - I prefer the EdP.
I've also smelled No. 5 on a man and he wore it beautifully.
Decide for yourself, you will know if it works for you just as you know when you wear a piece of clothing that works for you.
