How do you select which suit you're gonna wear?

A suit is a man's 'suit of armour' against the vagories of the day.
So wear the one that makes you feel the most confident for whatever function you have to perform.

No, I wear the same attire every day for work. I have to, it's my work uniform.

It's easy, I only have one....if I was going anywhere special I might buy another one....I dress smart casual ....

Depends who died or who's getting married. Black or brown.

You have more than one?

I don’t wear suits

Eenie meenie miney mo with my jeans and t-shirts.
