My dd can wear a costume to preschool on Halloween. We are in the Seattle area so not freezing cold but not exactly warm. She wants to wear her ballet recital outfit. How can I make a sleeveless tutu warm? Preschool is only 2.5 hours long. I was thinking about a nude long sleeve leotard underneath but that would mean wearing two leotards plus tights or leggings an that sounds like a potential disaster if she has to go potty. She didn’t like my cardigan idea.
