Effigies of ladies of the 13th or very early 14th centuries tended to all be very similarly dressed with a flowing gown and simple head covering, often with a wimple. The fact they they were depicted as large tomb effigies at all was sufficient testimony to their status. Most tombs of this vintage have been knocked around a bit, moved, and lost their colouring and gilding. They are ghosts of their former selves. The two ladies above are from Tideswell in Derbyshire.
It has been said that fashion was invented in the early 14th century, with clothing styles for men and women undergoing rapid change. Having the very latest in fashions was an insignia of not only wealth, but status and influence. If the missus was dressed in the latest crazy headgear and sleeves with a million buttons, then she was not only rich, she undoubtedly had someone to help her get dressed in the morning, like this lady from Bothamsall in Nottinghamshire.
In the days of sumptuary laws, if she was togged out in imported brocade, she was guaranteed to be of a certain status in the social hierarchy. The above is a replica of the brass to Margaret Peyton (1484) in Isleham, Cambridgeshire. These fashions changed so rapidly that the makers of effigies, whether brass or sculpted stone, were constantly updating their designs to keep up. Where the tomb has an inscription it is possible to create a chronology for these fashion changes but in the absence of one, I have doubts about identifying the tomb owner by cross referencing the date of death with the fashion design. It may date the effigy accurately, but it would depend on whether it was made before death (It's been done.), immediately after or some years after.
Here is a bit of gratuitous female bling from Methley, Yorkshire, because bling looks so good in alabaster. Amazing hat.
Something similar happened over the same period with the depiction of knights. The example above is an early 14th century effigy from West Tanfield, Yorkshire, turned out in chain mail. The evolution to plate armour and beyond took place as a series of specific details which resulted in a very different final result. Funerary effigies depicted these changing details of body armour, sword belts, shields, spurs in intricate detail.
