I'm not sure I'd file Ambre Sultan under skin scent -- that's a very strong fragrance! However, I've been digging on the two CdG Odeurs lately: 53 and 71. Although 71 has a bit more character, 53 is a galoxolide blast that makes your skin smell like a drier sheet. It's got some hilarious notes (oxygen, air, sand, light bulb etc).
Also, an odd little discovery as of late was L'Erbolario's Aqualiquida. I couldn't pull it off, but I was impressed by how it took old-school powder and transformed it into a minimalist ode to talc that was neither cloying not overblown. It actually reminded me of the CdG Odeurs.
