The sleeveless tunic, based on a knight's surcoat, was a popular clothing choice for medieval men. Then in the middle of the 13th century there was a brief fashion which added wide sleeves to the tunic and sometimes a hood, turning it into a garment called a gardecorps. This was intended to replace the surcoat and cloak, combining both into a single item, however it never really caught on. Still with sleeves and male fashion, the bag-sleeve for men, a wide, baggy sleeve snug at the wrist and shoulder, was popular for about twenty years around 1400, but again never really caught on.
All classes craved fashion, as can be seen by the various sumptuary laws passed in 1363 and 1463 which tried to stop 'lower' classes dressing in furs and certain fabrics and aping their 'betters'. Such acts made no difference as people loved to dress up.
Everyone, it seems, suffers for fashion, no matter how short-lived that fashion may be.
