I love big and slouchy! But structure for work is more formal and business like, not too boxy though because I am still young and boxy is too old for me.
How about softly structured? I love the look of slouchy bags, but they don't work as well for me as the structured ones. Nothing drives me crazy quite like having to fish around in my bag for an item, which has invariably fallen to the bottom. Structured works so much better. I do like softer leathers though -- nothing too hard. Not a fan of Saffiano leather, for example.
Structured but with soft leather for me. I like for the bag to keep its shape, but at the same time, I want the bag to be made in soft leather. Structured bag with stiff leather is not my cup of my tea.
Super slouchy is NOT for me. The leather feels great, but then my items will become cluttered and it'll become impossible to find stuff. This is why I'll never buy hobos.
