In no particular order, currently in my wardrobe:
Pour Homme HC
M7 and M7 Fresh
Opium Pour Homme, EDT and EDP
I used to have
Rive Gauche Pour Homme--not sure if I'll re-purchase but a great scent.
Kouros and many flankers--too self-consious to wear it now.
Pour Homme (regular concentration)--also great and will re-purchase this in spite of the HC.
Looking back through this, it's kind funny seeing mostly the same five responses. Then looking over at the YSL men's frag list, there's really only about 5 good ones....so not much choice when listing at top 5.
