Oh, my very artistic DD HATES her (public school) uniform. It was a serious downside of changing to this school for her. I have come around to it, in that it makes shopping and mornings easier. BTW, she is a synesthete (sees days, letters, and numbers in colors, as you mentioned).

She does her best with socks, jewelry, and hair accessories.

DS is uninterested in clothes, other than liking sea creature anything, so he won't care.
