I just looked up those simple chinos and they look great.
Do y'all size up on your Carharrts? For Dickies it's pretty much a given.
i only size up in the workwear, because to me it feels like they run small or at least shrink a bit after washing. got b51s or what they are called, the double knees. wip stuff always was more of as close to tts as possible. i got wip cargos, those fit wider at the waste than the workwear pants in the same waste size. but i oversize on all my pants. i am like a true 30 waist, but i generally wear 32. in terms of how wide the same size waist fits i'd go with this ranking from wide to narrow:
wip>dickies>carhartt workwear
but that's only my experience. so you could give it a tts shot, if you don't want to go overtly baggy.
