Mel, I spend a good chunk of my time in Renaissance garb.
When I saw the theme, I schwitzed a bit, cuz it's riiight up my alley.
My Ren vocal group went to BRC, en masse, in 2005(?).
The music was well received, but the only period garb we wore were hats, boots and belts. (The rest was lingerie and sarongs
Because English garb looks fab, but it is uncomfortable and HOT.
These styles you're looking at are English; try looking at early Ren Italian stuff; it's MUCH more desert appropriate.
Looser fit. Lighter fabrics. Tunics and floor length overdress vests ...
I own at least 15 bodices and corsets; I've spent exactly one hour in one at BRC ... it was so restrictive I had to shed it, and I'm used to the darn things!
