Cop Copine + dress label

A few days ago I bought a Cop Copine dress for a wedding. It had a handsome tag hanging from the inner label. Nothing unusual at this point. What puzzled me later is that unless I cut the string, I couldn’t find a way to take it off. But…how can that be? How strange to have a need to cut. I was stumped, so I put the dress aside.

Last night I pick it up again to dig further and voila, found that the conspicuous ball held the answer! It’s a fastener!
