Grey piqué Eton polo shirt — tagged L but fits M

I’m reselling this grey Eton polo. It’s in excellent used condition, having been worn gently and only on occasion (by me at least). It’s a lovely shirt, but I have several Eton polos and I find myself reaching more often for the colourful ones this hangs beside in my closet. The previous owner removed the materials tag, but it has a piqué finish and I’m guessing it’s 100 per cent cotton, like the other Eton polos I have. It has a three-button placket and the point collar has hidden buttons to ensure it sits up well. It was made in Romania. Though this is tagged as a large, I’ve listed it as a medium. I’m a slim large — I wear a slim-cut 16” shirt — and it juuuuust fits me. Please note the measurements in the photos — the bottom of the shirt is hemmed higher than my other Eton polos. My home is smoke- and pet-free. Thanks for looking.
