Personally I think it is all in the underlying scents and lightness or heaviness of the fragrance. For example, in spring, I am a fan of "Beautiful" by Este Lauder or "Oxygen" by Lanvin. Summer is great for Calvin Klein's "Escape" because of the strong floral scent. I am also a fan of Lacoste's "Pink". In the fall and winter, I like to go a little heavier with something like "Rapture" by Victoria Secret or "Mademoiselle" by Chanel.
