From cotton oversized flannel shirts to your most elaborate vision

A clean Cotton oversized flannel shirt with no branding is straightforward production. The stronger brief - and the more common one - layers in custom buttons, branded hardware, and construction detail that turns a basic silhouette into a private label piece. Our factory partners handle both ends, but the elaborate build is the norm for the brands we work with.
