I’m size M and I ordered size S. I would recommend a size down from your regular size just because it’s oversized as the image. Love the vivid red and it’s very fresh and soft

4’11 / 125lbs / 34 G I only wear shirts with a soft rayon and modal feel, it is a shorter fit for regular height women, but perfect for petites I got the Small for a slightly larger fit, to be casual with leggings or jeans. Knotting the front is perfection since the top has high side slits. Purchased pink & black. I will be getting the XS for dressier jean look, and extras of all the Small colors. JUST GET IT
