It's not hard to figure out what a signature look for me would be. We had a day during spirit week at my school where students dress like teachers and teachers dress like students. Two students (one of whom was my own daughter) chose this exact combination: maxi skirt, knit top, and scarf or cowl. Here's a (blurry!) photo of M and I in our swapped outfits:
Fabric- green knit from Joann's
Wearability- very high
Repeatability- I probably don't need another, but will probably make one anyway!
