Ugh tibalti call me anyways glimpse at his regular* design let me. Be self indulgent and explain
The weird spikes you see is just VERY stylized fur, specifically wolf fur: it is said that Georgia means “Land of the Wolves” and while Georgia does not have a national animal, many consider the wolf to be the national animal: Tybalt wearing the fur of one is meant to imply that he’s impulsive/hot-headed and untrustworthy.
Attached to the wolf fur is a Gazyr: it’s essentially gunpowder cartridges, which wouldn’t exist back when Romeo and Juliet takes place (Georgian Chokha’s only really adopted them in the 19th century), but they’re intricate little things that also hold a warning, I think I’d make the Gazyr’s a signature thing of the Capulets.
Overall Tybalt’s costume is a mix of Georgian theatre costumes (specifically those of Toreadors/Matadors) and a traditional Chokha
