Why wear bib shorts?

[RoadRaven]

Anyways I fell in love!! The chamois in them have gel in it, amazing! they never moved, and the straps have little hooks(like a convertable bra...) so you can unhook them to pee!!

Ah... just saw this "little hooks" comment...

So, how are the hooks there? Do you notice them on your shoulders? Is it a big chunky seam?
Or do you only know they are there when you need to try and find them?
