Being a superhot gentleman lawyer writer type, I have a certain standard of upkeep that must be maintained.
I own, I think ten colognes, more or less in order of preference:
Tommy for men
Pierre Caridin Black
Kenneth Cole Black
Perry Ellis 360 Red
Lucky no. 6
Calvin Klein Truth
Yves Saint Laurent Libre Homme
Chanel le Bleu eau de Parfum
Issey Miyake pour Homme
None of these are "cheap", and all are distinct. A cheap cologne does more damage than no smell at all.
Cologne should be worn in seven spots on the body: each wrist, two spots above the collarbone, behind each ear, and on the torso.
It should be applied approximately 30 minutes before coming into contact with anyone (unless they're your wife partner) as the dry-down will be strong, and the smell should be subtle and not immediately noticeable. If people turn their heads when you walk into a room, you are wearing too much. If the girl next to you breathes deeply and smiles but doesn't alter her position, then that's a good indication you are wearing the right amount.
Sweet and green colognes: CK Truth etc, are meant for the day. Usually, if a cologne is branded as "black" or "night" it is designed for, surprisingly the night. There is a science to this as the cold air impacts ones sent and sillage. Follow the rules. It is also worth observing that "sport" and sweeter, green colognes are generally designed to compliment your sweat, so are better worn in the summer. Warmly spiced colognes, like Farenheit, are Giorgio Acqua, work better in the Winter.
Versace Dreamer, Issey Miyake and Chanel le Bleu are universally aclaimed great all rounders, and this is reflected in their prices.
Something like YSN Libre Homme is quite spicey and strong, with pink pepper which many people are allergic too. Do no overwear this, and do not wear it in the day, as it will demonstrate how you have misconstrued your own sent.
I have one after-shave which is a YSN Libre Homme, which I use sparingly. I apply it after each shave, but a single drop on one finger is enough. It is meant to moisturise and leave a very thin scent on your skin, for someone who may venture close enough to sniff it. If you can smell your own aftershave, you are wearing way, way too much.
I have three shower-gels and a louffe; one of the gels is a YSN Libre Homme and I wear that on special occasions, the principles which apply to the after-shave apply here.
Generally, shower gel exists as a substitute to soap; Anything bought in a supermarket will be fine, but you should apply it to a louffe with some water and apply it all over. The process is meant to remove dry skin and clean your pours; the smell is mostly incidental and has little sillage, so pick something that you like, because others won't get any of it's benefits.
I have four deoderants: one an industrial strength role on which PREVENTS sweat, so I wear that if I am wearing a suit on a hot day. I have two body-sprays that are fairly generic, and one Chanel le Bleu roll on which I apply on special occasions.
If you would like, I can go through suit, tie, shirt attire. The rules for leather jackets, hair care, allowable growth and when to chew mint gum?
