Navy high-neck undershirt made of stretch material. - Brand: Under Armour - Size: YMD - Color: Navy - Design: High neck - Material: Stretch material - Use: For sports The back is mesh material. It's 140cm, but it feels a little small. My child says it's small, and they've only worn it about 5 times, but there's a stain!? on the right shoulder area. Other than that, it's relatively clean. Please check the photos. For those who understand that this is a used item, thank you.
