The majority of costume examples as seen in portraits and paintings from the time show the wearer, if not in court dress then the very best finery they could afford.These type of costumes may be available from specialist fancy dress costume hirer

I have tried to show examples of simple/everyday dress as worn by the peasant, yeoman or middle classes .It may be possible to construct something similar if you are skilled with a needle & thread!

For men :- trousers tied off below the knee, a large womans blouse with baggy sleeves , a suitable waistcoat and a hat will give the appearance of a yeoman farmer or tradesman
