The striped leggings are really classy. They all go great together.
The black leggings, on the other hand, look a little too simple. I mean, unless you want to go for the "Black is the new pink" look, then, umm, go for it! But come on, be serious, black hoodie and black leggings... a little too... black? Or a little too simple? Too simple indeed.
Yeah, I'm all game for the black ensemble. I wear black and black all the time. Throw in a colored tank for some variation. Maybe some colored Keds instead of black ones. My preference is sneakers, of course. But anyway, both are cute.
