A really interesting conversation.
I guess I'm in the minority here, because I still carry a wallet with cash and cards inside, cosmetic pouch, home and work keys, umbrella, sometimes a book, hand sanitizer, tissues, phone charger, face masks, small water bottle and I like having some extra space in my purse for whatever else. I live in a large city and use public transport to work every day.
Do I need a huge bag and different sized slg's for my daily crap? Probably not, but I'll continue using my medium to large sized bags. Simply cause I love them. Also, I'm just not comfortable with all the cash-less paying methods. I like whipping out the amount in cash or I pay with my debit card, if the amount is higher. Does that make me a dinosaur at 37? Maybe, but that's okay
I could use a utility belt for my stuff. But I'm not Batman...so not gonna happen. All these mini and micro bags are adorbs, but I simply have no use for them. I also hate stuffing my pants pockets with cards and keys and my phone...
Bottom line for me is that I will continue using and buying bags and slg's in sizes that suit my needs.
