I hear you on heavy bags. I still have too many Dooneys, Brahamins and a couple of Coach bags that I just don't carry any more since I retired. At 72, I find they are just too heavy, and for the few places that I go now, they're just too much. I bought a Michael Kors smaller coated cotton satchel that I like, but it's a bit small and the handles are awkward when using the shoulder strap.
A few weeks ago I pulled out a small Vera tote (I don't consider it small at all), and once again it's proving to be just what will work for me. Extremely lightweight, plenty of pockets, more room than I really need, and the pattern is subtle. I'd rather have more room than not enough room. I carry very little, but I like a lightweight, organized bag that is attractive and my old Vera is what's working for me right now.
