It's marketed to women. Of course men can wear it as well.
There is some similarity between this fragrance and Malle's Geranium Pour Monsieur. I think most men would prefer the Malle, though.
A "Diabolo" is a soft drink served in France that is lemonade with mint syrup added. Diabolo Rose adds the rose note to this.
So, think rose + citrus + mint and you will have a basic idea of Diabolo Rose.
I love it! Very refreshing.
