The thought came to me and I thought it was an interesting idea. It kinda makes me wish she and/or Clover would let their hair grow.
Don't get me wrong, I know their hair is already pretty much iconic and cute, and they wear their in a ponytail(s), bun(s), braid(s), etc. at times. But I think it'd be interesting if they change their hair lengths from time to time, or maybe each season.
