I bought this a little while ago, but I haven't worn it much, so it's in good condition. I removed the tag, so I don't know the brand name anymore. Both shoulders have cutouts, revealing a bit of skin. The left sleeve is short-sleeved, while the right sleeve has an A-line design. You can wear it alone in the summer, and in the transitional seasons, you can layer it with a long-sleeved T-shirt, allowing you to wear it for a long time.
