My very persnickety teenage daughter loves these.  I am going to have to buy another pair for her.  She wears them around the house as comfy lounge pants, under her jeans like long-underwear (she gets cold easy!), and in a few weeks when a dance style PE class starts up, she'll be wearing them for that.  She's not inclined to wear as such, but they would work well with a long sweater or tunic top.  A nice mid-weight material.
