I think it totally depends on how you wear them. If you wear them a La Hohan and pair leggings with a one-shoulder micromini sweater-"dress" and sky-high stilettos, then perhaps not. If you wear them with a cute denim skirt and wrap sweater with ankle or knee-length boots, you'd look babeliciously classy!
I am thinking of leggings, flats or boots and this tunic dress.
