If you like weirdly specific scents, you'll love the Maison Margiela Replica stuff. There's also a bunch of niche perfumeries like Zoologist that do all sorts of stuff that doesn't even necessarily smell good but is evocative. Even Dior made Fahrenheit, which smells very specifically and intentionally like iris and gasoline, and YSL made Kouros which is supposed to smell like a bed after gay sex.
