The smell of any food I like baking....especially cookies. :D Or the smell of food cooking when you walk into a restaurant, mmm.
My dogs, especially right after a bath, I love the smell of their fur, I like frito feet too ;)
Mountain air...wildflowers...pine trees...rain...leaves...sagebrush...basically any "outdoors" smell
Campfires
As for actual perfumes I rarely wear any, if I do its a light body spray, I don't like strong perfumes (on me, it doesn't bother me if others have it on)...I tend to like ones that smell like vanilla or fruit.
