central fighter, with red slit sleeves, blue mantle & skullcap, green gambeson body. The body of the garment is loose around the waist compared to covered breastplates around him. I've never seen something like this in the mid 1400s. He may be wearing maille or encased plate arms under the sleeves. Comments?

edit; found this one also from the froissart series, with many examples of slit sleeves, though no armour underneath; "Robert the Bruce meets Edward III"

I believe he is wearing a gown over his armor; it is commonly depicted in 15th century manuscripts. It is like the gown these men are wearing:

The gown may have different color sleeves or it may have a livery gown over it.

As James has noted, he is wearing a civilian gown over what appears to be a hauberk, and a livery (note the other fellows in green just like his), and a hood over that - his helmet over the hood.

As James notes, gowns or non-heraldic clothing being worn over armour seems to have been reasonably common in late 15th century art.

The fellow wearing a livery over what is possibly a jack would be the fellow with the red livery, center, bottom, with a blue scarf round his helmet.

Gowns and the like over armour are all over the Hungarian Illuminated Chronicle (14th c.) as well.
