I have started minimalizing/downsizing what I carry in terms of a handbag to only the essentials- small wallet, keys, phone, pen- for everyday. I have a separate tote I use during the week for work to carry iPad, papers, notebook, agenda, etc. So a smaller crossbody works for me at this stage of my life. I too have every size of speedy and initially I though 25cm was too small but once I got used to it, it was my favorite size for casual and weekend use. I love the lightness of the size.
My cars just arrived (on a holiday no less!)- it is a little gem- so glad I managed to snag one. A keeper for sure.
