I'm with this guy (not on the balmacaan, still want one of those). Would like to see a really textured cardigan with a shawl collar.Maybe some knitwear?
Another thing would be a waxed cotton jacket without bellows pockets. Or generally any outerwear that you already have except with more storage on the inside, moved there or added. The patch pockets from the peacoat would make a nice addition to the inside of almost every outer I have from you.
