This is a short-sleeved running tunic purchased from Lululemon Athletica. - Brand: Lululemon Athletica - Size: Equivalent to XL (I cut off the size tag, but I remember it was a 10) - Color: Gray ●Size: 10 (Not explicitly stated as the collar tag was cut off) I am including flat lay measurements for your reference. Bust: Approx. 49cm Length: Approx. 59cm Sleeve Length: Approx. 14cm (measured from the collar) Please note that these are amateur measurements, so slight errors may occur. This item was purchased at a shop when I participated in a marathon event abroad (Vancouver, Canada). I mainly wore it at the gym, and after quitting the gym, it has been stored in my closet without being used. Thank you for looking.
