In crafting historically accurate clothing, it is as important for the pattern to be accurate as it is for the embellishment. In tailoring, the pattern dictates what the end product will look like far more than any embellishment or even fabric choice.

There are no pattern manuscripts from 14th century Europe that I am aware of. So one must research extant materials and garments, experiment, and hope for enlightenment.
