Realising that all I need when I leave the house is my driving licence (also doubles as ID) and credit card, maybe some money in notes, these all fit easily into a shirt pocket. Carrying car keys is no problem. The shirts are men's. All else I wear is men's, except a couple of pairs of comfy women's shoes. I often put on a tie. Strange how, wearing skirts more than pants and shorts, being more formally dressed (than I have been in sweatshirt, T shirt and shorts) I'm way more comfortable.
