What is this jacket?

[Allen]

Is it a suit jacket, sport jacket or a blazer(I doubt it's the latter)?
The fabric feels kinda light, a tad bit more flimsy than most of my sport jackets and I know this is an important factor. However, the guy who gave it to me saying that it fits me(and it doesn't fit him, that was the point) didn't give me any trousers to go with it.
Opinions?

Welcome to Styleforum. It can never be a proper suit again without its original pants and is now considered an 'orphaned' suit jacket. If you insist on wearing it, then match with contrasting dress pants, chinos or jeans. In other words, you'll want to completely contrast the jackets dressiness. It's future now lays in creative combo's.

Thanks. I think I'll wear it because I'm young enough to get away with it and because it's plain, with no stripes.
I think I'll wear it with dark jeans, but do you have any tips on what kind of shirt would go best with this jacket? Should it be light or dark like the jeans?

This jacket is fuel for a fire....
It will never look good.

Certainly an orphaned suit jacket. Contrast and creativity are the only ways you'll be able to pull it off.
