I went to the ren fair recently, which got me interested in the specific historical inspirations of common “Renaissance Festival” clothes and consequently bugged my sister about her research so hard that it made us miss our turn
One common outfit you see (thanks to Amazon) is this modern take on the kirtle
On the left: Amazon. On the right: a recreation of what people actually wore. You can see how we have the same basic concept with a very different execution. This is what you would call a kirtle.
Another common ren fair look is the outer-wear stays. Always with the un-collared billowy undershirt.
I want to draw attention to the lacing. Stands to reason that costumers now would use contemporary lacing rather than that of previous eras. But check out even the romantic depictions of clothing from the 1870’s below this. No grommets. That’s just pure fabric baby.
Left: stays (underwear). Right: jumps (outerwear)
Stays are boned. Jumps are not. Stays/bodies were pretty expensive due to the craftsmanship, and a poor person would have budget for a single pair. You can imagine this investment was not as popular with women who did hard physical labor. Jumps got really popular in the mid-1700’s and largely replaced stays in working class fashion.
A brief history lesson: clothes are ephemeral; we lose them as they are worn out, cut down, repurposed, and thrown away. Before modern anthropology and modern record keeping, it was difficult for anyone to know what anyone else looked like in the past or even a country away. Words used to refer to one kind of garment kept being used even as that garment changed in structure and purpose over time. Even after paper became common enough for printing art, it wore out fast and art was lost. References were hard to get.
What we think of as “peasant garb” is actually the product of a game of telephone that travels back from Romantic Revival art, and many of those (urban) artists got their idea of what rural peasants wore from opera costumes. The costumers working at the opera were not going out to the country side to take notes on what farmers actually wore, nor did they want to. Opera is show biz, you want it to be evocative, but not ordinary. Their costumes would have been based on what urban folks were wearing, with extra little touches like a shepherds crook to make it look “rural”.
Below: some mid-to-late 1800’s artistic depictions of peasants wearing improbably nice fabrics/clothes (probably a reflection of opera costumes). The painting of the peasant girl on the right is wearing more-or-less jumps.
You can see how the romantic art depictions of unstructured vests eventually inspired the “medieval revival” styles of the 1960’s/1970’s which lives on in the ren fair. Not only the neckline of the vest, but the style of undershirt with an open neck and billowy sleeves.
Compare (unstructured, laced, outerwear):
Nobody wore that in the 1400’s or 1500’s, but they wore things that looked similar at a glance. When 1960’s artists went back looking for early modern/medieval styles to replicate, they mostly had a hodge podge of this art to reference and extrapolate from.
The fact that a historical laced kirtle with an over skirt looks a lot like stays worn on the outside, probably made this confusing for artists. Undershirts of the 1500’s were collared and high necked, however, with tighter sleeves.(Below, 1500’s kirtle)
One last example of 1800’s romanticism, this time depicting a contemporary girl. Looks familiar, right? We’re back at the ren fair, if you take the bonnet off.
TLDR; what we think of as “Renaissance” or even “medieval” peasant garb is actually a remix of the working class clothes from the 1800’s, with some confused memories of the kirtle from older art thrown in.
Structured stays? 1500’s. The blousy no-collar undershirt? 1700’s. The cross lacing? 1800’s.
Anyway. This image of peasants has always been costume & fantasy. That’s why I think it’s kind of fun that it reaches a terminus in the anachronism and fantasy of a Renaissance Festival.
