Hi Josie,
Using Ysatis is very brave in male mode.
I too rather like it and wear it occasionally. I came across it first when worn by our secretary at work. It was rather nice, sweet as you say, and certainly a feminine fragrance so I asked her what it was. I should also add that it is quite strong too! Fine in fem mode, but a bit of a giveaway as male I would have thought?
My other favourite at the moment is M&S Per Una. I have been wearing that a lot this year.
Emma.
