Try a pair of slim fit jeans with sneakers or chukkas. Almost any wash and colour of jeans works well with boots. You could also roll your jeans at the ankle.
For distressed and ripped jeans, sneakers work the best. Avoid boots and keep the rest of the outfit minimal with ripped jeans.
Tapered, slim-fit and dark coloured jeans work effortlessly with loafers, oxford and other formal shoes. Just make sure that your jeans are ankle-length or roll them up from the inside to hide the fold with these shoes.
Pair a dark coloured, regular fit jeans that almost looks like pants with your formal shoes. It would have been an outrageous idea back in the day but fashion is all about breaking rules, right?
