A full suit of plate would mark you out as a man at arms. A half harness, centered around a brigandine rather than a cuirasse is almost as much armour, and opens up many more possibilities.
I answered regarding the private tent concept on the Archive - an infantryman or coustillier would not have one, they would be either billeted with the other members of their lance, in either a tent, or just as likely someones barn or outbuilding. The size of issue of tents to the Burgundian army gives the impression that in many cases, perhaps only the mounted men at arms might have had tents. A German knight who served in Charles the Bolds army, up until after Grandson, shared a tent with a number of other men at arms, we know about it only because he complains in a letter about the garrison of Grandson (Swiss), being hanged in a walnut tree that their tent sat under, and how the corpses feet were bulging the tent roof, as the tree branch sagged - something he found repugnant.
A coutillier, when not in harness on duty, would dress in standard vcivil clothing. For someone who might even be a gentleman (a lot of coustilliers were apparently men at arms down on their luck, without the full equipment to serve as a man at arms, many were just middle class as well - one who saved Charles the Bolds life at Montlehery in 1465 was the son of a medical doctor), this would include mahioitered sleeved doublets, and likely a fashionable gown in wool. The fur would be something you would see late Autumn into Spring, lots of pleated gowns were not fur lined. IN Renee of Anjou's various books, you see a ton of pleated gowns without fur trim or lining, and if most of your activity is going to be in the Late Spring, Summer, or early Fall, you would want one like that before having one with fur.
You would wear shoes around camp,, your boots would be reserved for riding, when you were about to ride, or just after riding. A hat would be a must, probably a tall Flemish hat at this point in time.
If I were you, by the description you give, I would go for a nice brigandine, and a complete set of Italian export arms, sallet, and bevor, a standard of mail, voiders, and a mail skirt, and spend $$300-$400 on a pair of reproduction boots, instead of $1500 on a pair of complete legs with cased greaves.
