The one pair of bib shorts I have are Castelli, they're comfortable (except for that awful kiss pad they invented!), but like I mentioned before, a pain when you have to go to the bathroom. Mine have the two straps that go up and over your shoulders, they're very stretchy, flexible, and soft, so it never feels tight or constricting when you wear them, the straps end up sitting on the outside of each boob. And honestly, you don't even notice them while riding. So, what I end up doing is pulling each strap down while my jersey is still on, getting them back up takes a little more manuevering. In my regular clothes I'm often the type who will take my bra off at home without taking my shirt off, so it's the same idea as that. If you can master that you can master bibs haha... The benefit is no constricting waist band, but my other favorite pair of shorts are Assos, and they have a wide and flexible waistband and are honestly just as comfortable as my Castelli bib (with a better pad of course!)!
