Hi. I have a 2 oz size bottle of KL Homme by Karl Lagerfeld. I am very happy with this cologne. Here's my rundown:
KL Homme is a Winter / cold weather fragrance. It is quite heavy. One could wear it in warmer months, but I think it is better suited to the cold due to it's heaviness.
The fragrance is quite masculine, but it is soft. It's got a nice balance.
Sillage is good and longevity is also good. I don't ever feel as if it fades too fast. It doesn't last a really long time, so you may want to say average to good.
I think it is a great blind buy, especially at current prices if - here's the kicker - if you like masculine smelling fragrances. Karl is good at producing these, and this one does not dissapoint.
On topic: ever get a chance to whiff the older version of Photo? *That's* some piece of work!
Hope this helps.
Edit: I agree completely with foetidus' comments
