This one always bugs me. I guess it's really personal choice, but do you like your horses forelock under the brow band or over it?
I prefer my mare's forelock over the browband, but then you can't see the silver on her browband. But when her forelock is tucked under the browband, it looks messy (her hair).
I'm speaking as a Western rider.
But I guess English folks have the same issue, unless they braid the forelock first.
