Sorry for the delay in response! The Bella Court and the Regina can fit pretty much exactly the same things. The Bella Court will be a slightly tighter fit though because of the rounded corners, and may a take a tiny bit of tetris-ing to get it all in without bulging out the front or the back. That is one thing I cannot do with these bags - pack them so full they stretch or bulge out one of the sides or front/back, just a me thing.
I would say sunglasses would not fit in either of these bags. Unless I took a most of the other things out. I could probably have also gotten my small hand sanitizer bottle in there if I'd tried hard enough, easier for the Regina than the Bella Court certainly. Just depends on how loose or tight you can tolerate your items.
