I really prefer a cross body bag. My favorite right now is my preloved Chanel Gold Caviar WOC that is off at the spa right now. It's light, can be dressy or casual, and fits all my necessities.
I love all of my bags but I believe my favorite is my Gucci Soho shoulder bag in champagne with a gold chain strap. To me it just screams casual luxury.
I do really well with hobos such as LV's Delightful - they're just so comfortable and roomy inside. I like large totes too, but I find that they often have narrow straps that can dig in easily when the bag gets too full so I have to be careful not to weigh down my NF.
