Thank you for viewing! This is a puff sleeve made of pink satin fabric. It's very voluminous, so it covers your upper arms, which I was concerned about, and I was able to wear my dress with confidence, so I highly recommend it♡ I only used it once for a pre-wedding photo shoot. It's in very beautiful condition. There's elastic on both sides, so you can easily put it on and take it off just by putting it on your arms, and it holds firmly, so it never slipped down even once. I hope to pass it on to the next bride♪
