About 7 - 8 months ago i bought a Hugo Boss Cologne Gift Pack costing about $49.99 from kmart (however i had it reduced to $30 from a friend). The pack contained a Mens Spray cologne 75ml, as well as an afterhshave in a dab bottle 75ml. The fragrence is known as XY, and is a very nice strong, distinguished, yet easy on the nose smell, and best of all it lasts for hours and hours. In my case, girls from work as well as uni have made several comments as to how good it smells, and always try to guess the brand.
The Hugo Boss gift pack is great as most males will pile the cologne on like there's no tomorrow, and will as like i did, end up with an empty cologne, and half empty aftershave. You may be saying why is this good?, well the best thing about this is that the Afterhshave nearly smells the same as the cologne, and being a dab bottle, is very hard to waste, allowing some backup time to buy more cologne.
In my opinion, a man/boy/teen only needs one or two good colognes for those special events, and a few other cheap fake colognes for daily outings, where the wasteful male won't miss out on a nice smell. In the end of the day, make sure you smell good, it's not Metro, it's just good to smell nice.
