Black Jeans is discontinued, so it's hard to find sometimes.
Personally I love Black Jeans. Its over the top in the typical Versace way. It smells very arrid. I discovered this stuff one night while at a nightclub, perusing the bathroom attendants drobe which was laid out across the sinks. I tried Black Jeans, and it was love at first sniff. It kind of had an 80's smell to it, and as such I like wearing it to 80's nights at clubs. Definitely a fave for me.
Tucany I've never tried. Habit Rouge has its rabid fans, but this scent never did much for me. Its not bad, and while many would consider it a classic, against my trashy discontinued Black Jeans- I just think Black Jeans has more fun!
