It comes as no shock that the large tote trend is still strong. The best and easiest thing to reach as you're running out the door is a nice big leather tote with all your essentials. I use mine for work everyday and it's the best thing I've invested in.
If you're a bit hesitant to the $100+ price tag on most of these bags, Old Navy has a great option for you. A fab find indeed and also a Refinery29 pick, you can't go wrong with this faux-leather tote.
