I am on the prowl for a cross body bag in a fabulous color (lagoon, watermelon, raspberry maybe?) for summer. I like the Mona Lethal and the upcoming Something Unordinary, but how much can you cram into it? I need to fit a medium size wallet, sunglasses, cell phone, keys, small make up pouch, larger pouch with diapers (for son not me) and wipes, a small toy, and maybe a bottle. Would a Mona Lethal work or should I look at one of the bags with a regular shoulder strap and a c/b strap? What fits in your ML?
