The handkerchief top looks like the latest incarnation of the tunic. The uneven edge does add some visual interest, and while these hems do not look on the models like they lend themselves to belting, a thin belt would probably work well on a lot of the looks where you might want just a touch more definition. Otherwise, it’s a good, fun, Bohemian take that seems to demand bracelets and long necklaces.
(OK, so the middle one is more of a scarf top. This way you can see the difference. Scarf top, meet handkerchief top.)
