I definitely think skinny jeans would look great, but I'm also a fan of bootcuts with this type of top and a pair of wedge sandals. It just looks long and lean(at 5'4" I like any outfit that gives that illusion!)
Robin, for me I prefer a longer length tunic with leggings just for a bit more coverage. I think the structure of skinny jeans allows them to be worn with a bit shorter top, although I still most often prefer longer length tunics with any type of slim bottom. I don't know the technical difference, but for me a tunic is longer and provides more coverage with leggings.
