This is a.v.v's short-sleeved (5-minute sleeve) cut-and-sew top. Material: 62% rayon, 38% nylon Color: White It's made of a cool-to-the-touch material, and the hem has elastic, making it easy to pair with skirts or pants. The non-sticky material and simple design make it suitable for office wear under a jacket, etc. Since it's a 5-minute sleeve, you can wear it until autumn. I've only worn it 2 or 3 times, but I'm selling it because the size doesn't fit anymore. I think it's a slightly larger size M. I'm also selling a black one in a different color. I'm considering a discount for combined purchases. Please take a look at that one as well if you'd like.
