This is a Wonderful World apron (overskirt). There's a button only at the upper back (it cannot be worn as a skirt on its own). It's very cute when worn over two skirts to add volume. There is a small stain on the chest (see photo), please refrain from purchasing if you are concerned. KANEKO ISAO Kaneko Isao WONDERFUL WORLD Wonderful World PINK HOUSE Pink House Lolita
