Can we please use images of proper C14th/C15th brigandine rather than LARP/film pieces.
Real armour of this period has a Globus chest, made from two lung pieces (or in coat of plates a single breastpiece and a rear opening), with overlapping riveted plates behind the cloth and canvas support around and below it and in the rear. The rivets connect the individual plates to each other as well as binding to the cloth.
A simple breastplate is lighter and cheaper than brigandine.
An archer of limited means would first add an arming cap to his day clothes - with a helmet being the most important first piece of armour. If funds were available to procure more armour then a gambeson would follow. Couters and chains are an inexpensive and light way of protecting the arms from cuts, and I’d take those over hard body armour, and a simple breastplate would be the next item. - the back would be unprotected, and maille is very costly to make - though older examples could be endlessly repaired and recycled and might be affordable.
I’d expect to see everyone in an arming cap or helmet with arming cap, most with gambeson, and most of those with only limited pieces of harness or maille - breastplate and couter most commonly - some few with a pair of plates, and only the wealthiest with full harness, and with a mix of brigandine and white harness in the men at arms and knightly classes.
While men at arms and melee armed troops (spear/polearm/hand weapon and shield) would likely wear heavy gloves or gauntlets for hand protection (though this is a far more difficult technical task than protecting more robust and larger body parts, so effectiveness is limited), archers need manual dexterity and I’d expect more to not wear heavy gloves at all (or only to cover the back of the had/wrist and leave the fingers free in some eastern influences). Their hand protection comes from the use of buckler (which can be worn at the belt) alongside sword/messer/axe/mace/hammer, used to cover the hand when it is sent forward in an attack or defensive action, and to suppress the opponent’s hands when delivering a strike as an alternative.
