What servants may wear:
Fabric worth no more than two marks for the whole cloth. No gold, silver, embroidery, enamelware or silk. Women not to wear a veil worth more than 12d.
Could be worse though: Carters, ploughmen, drivers of livestock and dairymaids may only wear blanket and russet worth no more than 12d per ell and belts made from rope.
