My current nappy bag has 2 parts - a small little backpack and a larger one (they zip together if I needed to, but have never used it this way). If I use the smaller one I don't bother with my handbag (this is for quick trips down the road) I just put my purse in the bag as well. But if I'm going to be out for a couple of hours I take the bigger bag, then I usually then take a little tote type bag for the purse and lippy and brush so I don't have to be digging around in the big nappy bag trying to find them.
