I've been trying to incorporate blazers but it's a new thing for me so I need some help 
First one - Does this fit / can I wear it with jeans? The only way I can really picture it is with pressed white trousers with a lot of extra length. Can I wear it with anything that's not all white? I sorta love it but it's hard to style and it fits bigger than other MMM blazers I've tried so I'm not even sure it's the right size.

And this one, also MMM ($100 on ebay) - it fits a lot slimmer, and I'm a lot more confident in being able to pull this one off, but is it too formal to wear with jeans? It's double-vented. It badly needs a press which is why the lapels and back are all fucked up. If I can't wear it with jeans, can I do stacked trousers + t-shirt?
Excuse the unintentional benesyed pose.
