If you could have a set of tack (bridle, reins, saddle, and breastcollar) that looked like ANYTHING in ANY style, what would you want? Let your imagination run wild.
Celtic or Elven fantasy
Greek or Roman
Spikes and studs
Themed bridle/halter combo unlike the boring, plain ones
... or something else of your own design
Specify English or Western or a combination or maybe something else entirely, with or without a cavesson, throatlatch, browband/split ear, horn, skirt, etc...
