Currently use a Rachel Fossil Satchel which I adore. It's just not big enough but I do like wearing it cross body with a chunky scarf. I like the structure of the satchel and how roomy it is. My planner doesn't fit with my purse though.
I've found a bag by catwalk, but not heard of them as a brand before.
