Late to the conversation, and hello after being away for a long time. Just wanted to chime in that I was hesitant to use the large Belly for a long time after I got it, but once it softens up, it is a very user-friendly bag. My friend had the smaller Belly and it was fantastic on her and of the two sizes, I think the smaller one would be better for formal/evening functions. At 5'2'' and 5'3'' my sis and I use the large Belly and enjoy its functionality. It can hold all the essentials including a water bottle and a book.
