Aye aye, Captain.

Being a life long yachtie, I could not bring myself to wear a proper blazer. Too much emotional baggage.

The one blazer I have has gray horn buttons, so I can wear it basically any occasion imaginable, short of black tie. The gold buttons will bring the range down a bit. Still can go from khakis to grey wool trou I believe. I think jeans are out with the brass though.

...I suspect there was plenty of 'wood' but it wasn't of the bowling variety.

With a cravat, you look like Stan and Pam Herbert

A blazer's a basic item in my world, suitable for any activity that doesn't involve a job or grief. (In other words, don't wear a blazer to a job interview or a funeral.)

Blazer with chinos is the casual side of it. Boring but safe. Blazer with jeans is the Warhol effect. Oh how edgy. Gaah.

Blazer with linen pants, or gabardine, or flannels can be quite elegant.

Blazer with grey trousers is frequently maligned as the security guard look. All I can say is if you do it right nobody's going to mistake you for security.

Blazer over polo shirt with rumpled chinos and trashed boat shoes is okay if you have a thousand dollar bill stapled to your forehead. Otherwise it's an unfortunate look.

That is all.

The blazer is more than that, but you need a certain sangfroid & charisma to do it, otherwise you're just another wannabe down at the sport's club.

It looks very ceremonial - out of place in a work environment
