Shimmery gold and purple one shoulder top

So pretty! Semi-sheer purple flowy material with a gold sheen. One arm is a 3/4 sleeve with an elastic wrist so it stays put, one is an open strapless side. Can be worn as an off the shoulder too. (See photo) Only been worn a few times, no flaws, looks brand new! Brand is "cherish", not listed brand. From a boutique 💖
