Anybody want to show me a picture of form-fitting medieval dresses?
Some tight(er) clothing does exist for women after around 1200; but, again, nobody goes to battle in that. You don't just go chill out in it.
One essential part of womens' formal wear that BM players rarely include: the hat! Giant hats were in for a long time. Especially pointy ones.
Tight clothing was really more for men than women.
Silk is definitely possible, but expensive. It is true that rulers might demand it: but even high nobles like BM nobles should not be regularly running around in silk clothing. Silk is an emperor's formal wear (unless you have a special RP for your realm that establishes you as a silk-producing region).
Note that, in my mind, if a fashion only BEGINS to appear in 1300-1400, it isn't medieval. I would define medieval as widely popular by 1300-1400 at the LATEST. None of this 1492 or 1452 nonsense. BM is pre-gunpowder, so we should be thinking pre-Hundred-Years-War in terms of mood and dress. 800-1200 is the best bet for cultural models.
