But you put her in a mid-late 15th century Burgundian gown and hennin, beautiful garments but from at least a century after she died.

Like I’ve said multiple times, I’m not a historian - or a costume designer, or a trained artist, or, well, you get the picture. I’ll get things wrong.
If you have recommendations for historical costume design resources, please let me know. I mostly rely on Racinet’s work (I even have the big stonkin’ hardcover copies), but it’s got plenty of gaps in its knowledge. Every time I’ve talked to a costume designer in LA about their research methods, it’s involved travel to a lot of difficult-to-access libraries and an untenable amount of research per entry.
