Was going to start a new thread for recommendations but found this so may as well continue here.
A few particular ones I like:
Azzaro Pour Homme - this is IMO the most masculine smelling fragrance out there. It is awesome, and not overly expensive. This is my go-to job interview fragrance or if I have to do something important at work where I have to feel like a boss, it just surrounds you with an aura of confidence and presence and it just smells great. I think this is the best route in to classic masculines for a younger man, it is very different from what you might be used to with One Million, Le Male, Acqua Di Gio, Boss Bottled etc but it is more refined than the traditional "powerhouse" masculines.
Caron Pour Un Homme - this kind of a more sophisticated upmarket version of Le Male, it's basically a lavender fragrance but it is done brilliantly, it smells very calming and pleasant and I sometimes like to spray this at night before going to bed. Makes you feel very in control and cool. If you like Le Male as a "clubbing" scent then CPUH is more the refined gentleman version.
Mugler Cologne - clean and citrusy, this is my no.1 favourite summer fragrance and I wear it quite often in other seasons too. It's quite underrated but really versatile, I wear it a lot for the office and this does attract a lot of compliments. Lasts for ages and I love the smell of it hanging round on my worn t shirts.
Creed Aventus - ok this one is hyped on the internet as some kind of magic love potion but it is based on reality, it really smells great. If you hear a girl going on about some guy that smelled sooooo good, ask "was it like smoky pineapple?"....yep, its Aventus. The down side of this is it is expensive especially for students to afford, and the smaller (£95) bottles don't seem to be available as much now so you're looking at spending £170 or whatever - its a lot.
Creed Green Irish Tweed - A brilliant office scent, you can smell that this is a refined and interesting fragrance, downside is similar price point to Aventus and there are other fragrances out there that smell similar (Cool Water, Aspen) for much cheaper. GIT is better than them but if you are on a budget it may be a bit steep.
Kouros - simply the most sexual fragrance there is. It's very difficult to describe if you don't recognise it but its basically like a mixture of light perfume mixed with spunky testosterone aura, it is uber masculine and very suggestive. But it's really hard to wear right and goes to overkill very quickly because its very strong. I use one full spray to the stomach and let the scent just work its way out on its own and you just get the raunchy hints of it in stages, two sprays is pushing it, if you do three or more it just smells wrong.
Old Spice Whitewater - IMO the best value for money fragrance there is, seriously this is right up with the best of the 'fresh/acquatic' fragrances and it costs just a few quid, if you can't find it in a store just buy some online. Honestly every time I have recommended this to a friend they have said the same thing, it's incredible for its price point. I personally love Old Spice Original as well but Whitewater is a more modern and mainstream scent.
Davidoff Cool Water - this is fantastic value for money, yes its popular but its one of the safest bets out there for making yourself smell clean, fresh and vibrant
Beckham Instinct - like Mugler Cologne it's underrated and a great safe bet for all situations that does attract compliments, people turn their noses up at it because its Beckham but IMO top class
