as with KIIM i think black bridles look smart on any horse. however, i have a brown bridle that blends perfectly with my bay stb and it looks really nice.
my pick would still be black though unless you want one of those funky colours as a training bridle. theyre cool :) if so then i would say blue or purple going by your girls colour :) maybe even yellow...or green would look good too...even red would contrast nicely...ah, i dunno. im picturing every colour looking good at the moment lol
