That flowered top is very pretty. I could do a light wash baggy jean with it, but not the ripped up ones you have on. How about a white tanktop instead of the black? ones
The ripped up jeans and the black tank completely conflict with the sweet top. I think you'd be much better off with a pair of dark skinnies or bootcuts and some cute nude or light pink flats.
I like the floral tank, but not the black tank underneath it (takes away from the sweetness of the top). The top would look cute with dark wash skinnies and ballet flats :)
