The pieces are very nice and the color scheme is spot on, but despite the fact that the individual items up top (OCBD, knit tie) are rather casual, the top half is still too formal for jeans. I'm not someone who is 100% against jeans + tie, I just think the formality coherence needs to be near perfect to pull it off. There was actually a jeans and tie "train wreck" challenge a few months back. PTO did a nice write up on one of the better entries. Link.
