Designers Daniel Silver and Steven Cox are known for mixing patters from season to season, but in their Spring/Summer'13 show, they really hit the mark not only with their plaid on plaid mash-ups, but their tonal and denim on denim looks as well. You can bet that you'll see a few guys trying to pull this off in the streets, but maybe you should just leave this to the runway unless you are doing to cop the actual Duckie Brown pieces.
