I have a man bag, and I'm proud !! A grey fabric one, with a black, red and white strap.
Main reson is for the summer, because I found that increasingly, the main reason I wore a coat was to have somewhere to put all my stuff, like wallets, keys, phones, notepads, etc. and didn't like having my trousers stuffed with them instead. Bought a bag off eBay last summer and haven't looked back.....
Some people take the Mick, but that's their problem, not mine !!
