Yes, you should be able to fit all of those items into the pico belt. I have the nano belt in taupe and love it! It’s the perfect neutral—- more versatile than black imo. I’ve tried both sizes on but felt that for the price the nano belt made more sense. Unless you prefer a mini bag, I would go with the nano belt. It’s nice to have the option to carry a bit more. In my opinion, the nano looks great worn crossbody, handheld and in the crook of the arm. The pico belt looks best worn crossbody. It’s definitely cute but the size just seems more trendy than the nano belt.
