Short, tunic-style dresses?
I don't wear leggings but have really enjoyed wearing dresses with opaque tights lately. I tried on this
dress last weekend at the local Lane Bryant and LOVED it. It runs a bit big, I think, since the 22-24 fit me well.
Anyway, it was really short on me and I am 5'4". Mid-thigh in the middle, perhaps? And would be great with leggings. They had a bunch of other short sweater dresses and tunics that would work with leggings, too.
Oh, or handkerchief hem tunics. I really like them, but you need fitted bottoms to wear with them or they just look schlumpy.
