This feels super high-quality. I ordered the medium (F, 5'2", 160 lbs) and it fits perfectly.
I do wish the waist tie was a bit longer as it's not quite long enough to do more than a basic knot. I found I prefer reversing the tie in order to knot in the back, not the front, as this seems to make the big embroidery panels lie flatter and displays them better.
The side slits are also QUITE high. They come WELL above my bellybutton, even higher when I sit down. I'm still showing skin even in my highest of high-waisted pants. I'm not comfortable wearing this tunic without a shirt/cami underneath it. This isn't a problem per se, but definitely something to consider.
All in all, tho, I love this and immediately ordered a second tunic in a different color.
