Other than the Canadian tuxedo, what other ways are there to get a not-suit but suit look? Matching jacket and pants meant to be worn together, but with less formality than a regular suit.
Basically I'm unlikely to attend any weddings soon and (hopefully) no interviews so I'm looking for something suit-like or casual suits, but that won't give off heavy corpo/formal vibes. Something to wear out to dress up a bit for dinner, parties, museum stroll, or when the mood strikes. Open to any material & texture.
Things I own that fit the slot: black corduroy blazer, light chore coat - but neither has matching pants.
Would prefer something that could be had second-hand and either worn as-is or tailored.
