On one hand it makes sense that medieval european social relations imply, well, medieval european social relations and it makes sense to use your novel (or your show) to examine those.
On the other I can relate to many people wanting to see women in medieval fantasy to be represented in some other way than constant misery porn.
Actual medieval Europe outfits and decorations done by lords for the most popular feast days were garish as fuuuuuuuuuuuuuuck. They also had a habit of making entire edible palaces with edible figures and accessories.
