As described in an interview with Giant Magazine:
"A BKc man wears classic clothing incorporating unique items that add elements of youth and pop. There are various ways to do so such as decorating the wrist (bracelets and handkerchiefs), a beautiful ring, good pair of rolled denim/khakis, classic shoes (desert boots, Converses, loafer), tee with strong detail, fabric wrapped around the bicep, hat (fedora, paperboy cap) and a vintage belt."
With their website-come-blog about the business, I can't find a reason not to want to join their Circus.
