Would love to see a pic, BBC. Have thought about going smaller than a B30 but I am convinced that only my sunglasses would fit in a tiny bag.
Believe it or not I have other lux clutches that cannot even fit my iPhone! I think that has me scared of small bags.
Ah, Saturdays are "bench" days for me as I spend most of the day sitting on a bench waiting...an hour drive, then DS1 has dance 10-11 and acting 11-3, then back home. So this is the best I can do for now. A pic showing the size next to a soda bottle (not enough caffeine for me on Saturdays):

And then what's inside: Bastia (forgot my calvi), pouch for several lipsticks, small silkin, iPhone, letter from yesterday's mail ([emoji6]), clif bar, checkbook, small Purell, cough drops, and there is still plenty of room even when I close the straps. The iPad mini will fit easily as well:
