I've been wearing the same perfume for about three years, and I suspect I'll keep wearing it for as long as it's manufactured! It's Evelyn Rose by Crabtree and Evelyn:

It combines all of my favourite scents: fresh rose, with hints of peony, violet, jasmine, and peach. It smells like an old-fashioned rose still on the bush. I LOVE it. It's funny, my personality and interests suggest I should like a more edgy, herbal, citrusy, green perfume or a chipre but this is what I love. It's fresh, sweet but not too sweet, and feminine. I grew up with parents who loved to garden, I adore fresh flowers, and my granfmother always grew different roses and would let me take one home with me every time I visited, so I guess it makes sense.
What fragrance do you wear the most and why?
