cantoresq – “I do have one particular Shabbat practice though it’s not a hard and fast rule. I prefer wearing colored shirts on Shabbat. I think they are nicer than plain white. Thus I save them for Shabbat or Yom Tov.”
I too have a minhag to save my better suits for Shabbat or Yom Tov and colored shirts would just not due them justice. My colored shirts do go well with my work suits.
