I tried on 5 Terry shorts for comparison.
I am generally a XXL in Terry, though maybe more on the cusp between XL and XXL, so I tried this in XL (no XXL available).
They were just a hair snug in the legs, but not too bad, and plenty comfortable with the bib style and laser cut leg holes. The top had plenty of room, was maybe even a touch large (though I am only 5'5" wearing an XL), but I'm sure a jersey would keep it all in place. It wasn't too big, I would call it a touch loose/comfortable, and it's probably better than being too tight given the halter style around the back of the neck.
Speaking of which, I love that they went with this halter style for women, genius!
I would suggest pairing with a high neck jersey though, such as the Sheebeast Divine, or similar.
Ultimately I decided to go with the Peleton Hi Vis and the Breakaway shorts, but these were 3rd on my list, so if money were no object I probably would have kept them, too. And if I do change my mind and decide I want a bib short later, I would definitely come back to get these.
