Iso, unless you work in a specifically CBD environment, tweed is OK. It may be acknowledged or overtly noticed as a seasonal choice, but so will a linen suit. If your environment allows it, and those are your preferences, then go for it.
Disclaimer: I say this as a dude from San Francisco, where individuality is encouraged. You may want to mitigate your fabric choices with muted colors like Clags and keep the patterns sober. Otherwise, the world is your oyster.
