From designer fragrances you could check out:
These have a classy chic vibe and can be worn to work or special occasions.
Gucci Pour Homme II - A tea based scent that wears close to you and smells good. You can wear this anytime/anywhere.
Fahrenheit - It's great but not for everyone, worth checking out.
Rive Gauche - This has that barbershop vibe and is a good masculine and its very popular here on basenotes.
Burberry London - Tobacco and leather with a port wine smell. Solid fragrance though longevity not so good.
For a special awesome designer fragrance that gets a lots of love and is one of my favorites then it is:
Guerlains L'Instant Extreme Pour Homme - Cocoa and vanille combo that lasts for ages and projects really well. Awesome frag.
For Niche which is where things get expensive:
Creeds Green Irish Tweed - This is a wow fragrance when smelled for the first time.
Creeds Aventus - A smoky pineapple frag with apple and jasmine in the background.
Amouage Jubilation - A very classy scent with top notch ingredients.
Tom Fords Tobacco Vanille - Smells great though it is sweet and strong.
