AXESQUIN ELEMENTS Short Sleeve T-Shirt

Purchased online recently, but it was only tried on as the sizing was incorrect.
Size is (1).
The manufacturer lists it as XS, but based on the fit and the manufacturer's measurements, I believe it's an S size.
It has an oversized cut, so it feels loose when worn.
Other colors in the same size are also listed.

Product HP:
When you reach the terrace of a mountain lodge halfway up a ridge after crossing a mountain pass, you'll want to take off your shirt and cool down. In such a situation, this short-sleeve T-shirt made with Asahi Kasei's SUREDRY∞, which excels in sweat absorption and quick drying, will effectively dry your sweat. It features a natural texture and the comfort of a loose fit. While the design is simple, it subtly makes a statement with the Hike on Alternative loop tag at the hem. With a wide range of colors available, you'll want to wear it every day, whether in the mountains or in the city.
