The Suit Jacket/Sports Jacket Debate

Hi guys, just wondered what the varying views are on wearing a suit jacket in a more casual setting?

I just purchased a navy Calvin Klein suit the other day. Thing is, the jacket is the best fitting jacket I've ever bought off the peg and it seems a shame just to wear it in formal settings. It's 100% wool, a fairly contemporary cut and not remotely shiny, so I don't see the obstacle. What do the more satorially-inclined gents here think?

I'm gagging to wear it next summer with white trousers, a summer scarf and loafers.

Cheers

This site advocates splitting suits up as separates, so I don't see the issue really.

Very much depends on the cut of the jacket imo. Some suit jackets should only be worn with suits e.g. when they are very structured, or a bit longer at the back. If the suit you have is quite a contemporary cut, then it might look great with what you described. Hard to say without seeing a pic though.

In theory, I'm all up for splitting suit jackets. Like Nat says though, it depends on the fit/cut. I have a gorgeous Navy suit jacket from Peter Werth, which (due to the fit / length) just doesn't look right when mixed.
