I purchased this from the ZARA online shop a few years ago. I've worn it a few times, but I think it's in good condition (^^) You can still wear it! The waist is elastic, and the buttons and string are decorative. The buttons do not come undone. I am selling it because it no longer fits. *Please note that overseas products may have loose threads or imperfect stitching. Please purchase only if you understand this. m(_ _)m
