I've worn this about 2 or 3 times. I'm also selling several similar items. I'm happy to combine shipping if you buy multiple items. It's still in very good condition, but it has been worn a few times. Please understand that it is not unused before purchasing. Although it's size XS, it fits like a size S, so it should be fine for someone who usually wears S. It can be worn by someone who usually wears M, but it will be a snug fit! 【Brand Features】 This top is a collaboration between adidas and Stella McCartney, combining style and functionality. In particular, the mesh material provides breathability and ensures a comfortable fit. 【Design】 The simple and refined white design is easy to coordinate with various outfits, making it perfect for training or everyday wear. The mesh back is a distinctive feature that enhances comfort during exercise. 【Size and Fit】 Size XS, with a body-hugging design. Lightweight and easy to move in, it's perfect for an active lifestyle. - Brand: adidas - Model Name: STELLA McCARTNEY - Size: XS - Material: Mesh - Color: White Thank you for looking.
