I have a larger than average sample of the DKNY Pure and I like it very much. It's light, kind of springy. I can see me wearing it on a day where it might be raining and I want something to keep me feeling calm, easy going, etc. But like you... I am not sure I'd buy a full size since I wear it so little and the bottle I do have will probably last more than a year or two.
I recently got a new perfume from Avon (their mark. division) called "Ibiza Sol" that I really really like. I wish they had it in a body lotion as well since it has a tendency to fade very fast.
Tomorrow I have an afternoon free. If I'm up to it, I may hit my local Macy's to see what they have new for the season and take a couple of samples. Can't do that all day, though. My nose sniffer senses will be fried after a while!! (Coffee beans... bring coffee beans!!)
