Is there a really good collection of men and women renaissance period Clothing to purchase? Also might consider buying some for my 11-year-old daughter as well???

Yes! There are several clothing stands throughout the fair- some specialize in corsetry, armor, kilts etc. Admittedly it is understandably expensive since most of these stands are run by small businesses, but if you're looking for something cheaper shein does actually have some good options

Stop by Dress Your Dreams shop on the shire. Lady Susan has a huge selection of renaissance clothing for adults and is also one of the few that has children's sizes. Building 510 on the PARF map.

Yes, there is a variety, more so for women than man. Renaissance clothing teters on the age. There might be less for a child but there are choices. I dress as a farmer, plain and simple

Yes, tons of vendors selling clothing and miscellaneous period items.
