I start to violently crap blood whenever I hear one of those costume designers that sound like Edna Mode on steroids harp on about how they had to make costumes for a historical piece set in the days of Louis XIV and Versailles and despite having a mountain of period costume references they insist on adding Maori-style facial tattoos or 11th century Pecheneg embroidery, while the hairstyles are a mix of 17th century Cherokee, Dark Age Elbonian with West African hair beads made from beetle shells they found in a tiny bazaar in Southern Mali that specializes in ethnic tchotchkes and dysentery to make it "richer and more visually interesting" ...
As a kid seeing Sabata toting a custom derringer was awesome, it was notable, rare and unusual and that made it so much more special, unlike today where EVERY character has a custom-designer gun, custom-designer sword, custom-designer clothing etc ...
And then there is the race to add more detail, complexity, layers, textures than previous costumes, ever more baroque, ever more complex ...
