Where can I find guys pants that are the same as Mick's jacket? Briefly looked in some shops, while in NYC, for the Brooklyn and Newarks shows. Couldn't find anything.
I just did a couple of searches on Amazon and found nothing like you're looking for. Probably your best bet would be to find some sort of custom clothing shop in your area and ask if they could make a pair for you. Any shop that does alterations would probably have some insight as well. Although very few of us here would even know what kind of material to start with, an actual tailor would have knowledge and insight that most of us wouldn't even know to consider.
