Here is the link to the blazer but what colour trousers/jeans would pair with it?
I think black jeans would clash with it with a white shirt underneath?
I dig the patterned linen but the jacket is a bit short for my taste and the lapels are tiny. Too GQ looking. Anyway, if it were me the first thing I would do is replace the buttons with MOP, then I'd get a cream colored pair of chinos and wear the crap out of it in summer if this is a jacket you like.
That's why I caveated what I said. That style of jacket will not get a lot of love here, but I understand that there are some contexts in which it would be more appropriate. For instance someone who is 19 rather than someone who is in his 30s like me lol. Anyway, if you have your mind set on this then enjoy.
