Need advice about overalls

Hey team.

I am looking to buy denim bib-and-brace overalls. I need them to have a deep enough crotch to accommodate cloth diapers - for reference, two flat terry cloth diapers (I will probably be wearing less diapering than this but I will need them to accommodate this much).

Since I've never owned overalls, I don't know how realistic this is. The average overalls look pretty loose around the body to me - is it possible that the average pair of overalls will have a sufficiently deep crotch for this, or am I likely to need to buy a specific brand / from a specific supplier? Alternatively, is there any specific keyword that might describe the cut of a pair of overalls that might have this kind of fit?

Thanks very much in advance for your advice.
