that’s chunky overshirt territory, IMO:
I’d agree with this, though the one linked has an odd-shaped cut to my eye.
Also, the word “overshirt” seems to get used for a lot of what I’d just call “shirts” these days.
I have a nice quilted Finisterre one which is actually jacket territory. But like that Hebtroco one it’s cut a little shorter than I’d ideally like.
Take my advice under caution though. I actually do wear a jacket like Crocket’s in the Miami Vice link above (but blue).
