Uniqlo Airism Seamless Long T-Shirt, size S and L, set of two short-sleeved T-shirts in black and khaki. I can wear size S without any problems, even though I usually wear size L. I think it's good to wear size S with skirts and pants, and size L for yoga or Pilates for a more relaxed fit. It feels cool and comfortable even when you sweat. Both have only been used once or twice. - Brand: UNIQLO - Size: L Khaki - Size: S Black Thank you for looking.
