Keep jacket (it's great)/burn trousers--leg opening is waaaaaaaaaaaaaaay too tight.
Haha, they're quite tapered to prevent the legs from billowing awkwardly when you when walk, so there's plenty of room where it's necessary Believe it or not, but they're actually some of the most comfortable jeans I own, due to the high rise.
Darker pocket square with more colour - this one just blends into the jacket.
White shirt with French cuffs and a tie are really out of place with jeans.
I'm not a fan of navy trousers and don't much like them with grey jackets. If your PoW check had more elements of blue it might make more sense but otherwise I'd stick to medium grey/charcoal here.
Nope, the linen SC was never part of a suit. The linen is actually pretty coarse, a lot rougher than a linen suit I have for example. Besides, odd glen plaid jackets are pretty common nowadays, right?
I did not expressed myself in best way, sorry, I'll try to be more precise this time.
In my opinion, this pattern is exclusive to suitings when it's in a small/medium scale, such as yours. Also, some would say that a patterned linen should not even exist, but I'm not with those.
