Honestly you'd have to prise my B30 from my cold dead fingers to get me to part with it!
I don't give two hoots about what's on trend, as far as I'm concerned my medium sized (in my opinion) tote is perfect for a full day out. I still love the B35, but unfortunately a bag of that size and weight doesn't work unless it fits on my shoulder.
In the UK, with the associated weather and at my age I need glasses, (variofocal) sunglasses, umbrella, card holder, keys, lipstick, mirror, tissues, tablets (the medicinal kind

), vape (sorry!) and enough room to pop in a couple of smaller purchases (hate buying carrier bags).
My mini Evie is perfect for a short trip when I need to be hands free.. supermarket shop for instance, but for all day not so much. No way could I leave the house with a mini Kelly and not be carrying a whole bunch of stuff separately!!
