I’ve started to collect images of Dutch and Flemish women (and some men) on a pinterest board. Partially for the convenience and also to have somewhere to easily peruse ideas and styles.
Check out the Dutch clothing board and the Lucas van Leyden board if you’re so inclined.
I’m also collecting images of 15th century kirtles, as they’re comfy and a plausible under garment for the style up until about 1520.
