YVES SAINT LAURENTLHomme for Men, 100 ml - EDT Spray

I need three fragrances: a soft and fresh for the day, another sweet for night and one that is sexy for a date with girls. What would you recommend?

Is this real ?? Because I order this one and it seems a bit weak I mean the scent.

Is this a perfume version or an EDT?

Is this original or a knock off?
