This. If you are going to do the look that @gdl203 recommends
1) Go tieless, and wear a shirt that has a collar that looks great open. I personally like Barba, but any number of companies make shirts that will work.
2) Get shoes that work with jeans.
The first is really easy. the second, seemingly hard for a lot of guys in classic menswear to get. Something like chelsea boots, or jodhphurs, or of course, chukkas/desert boots. But not high shine double monkstraps, at least not for most guys. I've seen some cool cats do it with loafers well, but I can't.
