Nice topic Blu.
I'm a Calvin Klein stan from way back.
I love Eternity. I got the limited edition Eternity Summer (EDP) in Paris about 2 years ago. It was lighter and fresher, but the original is still the best for me. It smells like luxury, money and sexy times (I know it sounds ridiculous). Other wonderful CKs are Escape, Obsession and CK 1. I don't really like any of the CK fragrances he'd made since 2000. 1990s ftw!
For sommer net, I like Versace Red Jeans. It smells fresh, fun and its really affordable, so I keep some at work, in the car and in my "just in case" kuier bag.
JP Gaultier I love to bits but he's not my regular. I like Classique (the one shaped like a lady's bust & torso) and Fragile which is the best bottle and bet Gaultier fragrance (dome shaped bottle with a black statuette of a woman & lots of glitter inside like a snow globe).
For my man I like the male bust/torso Gaultier in that silver tin and Aramis Life.
