You know, it's gotten to the point where I wear whatever I'm in the mood for at any time of year. Except for the very hottest dog days when I usually only wear a very light cologne type fragrance, or maybe just body powder. I've notcied that many people have their "fall" and "winter" fragrances, and they generally seem to be spicy orientals and the more resinous chypres. "Summer" fragrances might be lighter versions of their winter scents. Caleche eau delicat, for example. Or, if they love florals they might look forward to wearing more florals in spring and summer. But personally, and I don't know how many others are like me, I just wear whatever fragrance phase I'm in the moment. I might be into orientals, and it might happen to be summer but so what. Right now I'm loving "light fresh" fragrances, and it's certainly getting quite cool and autumnal here but I don't care, I spend most of my life in an artificially cooled and heated environment anyway.
p.s. Sorry I didn't quite answer your question, but I know you will get lots of good advice here from others! just my two cents.
