I'm about to make my first investment bag purchase. I don't know where to start. I'm aiming to buy a beautifully made leather handbag every 5 years or so, and eventually hand them down to my daughters. My budget is £500, and I'd like it to be something that I can use day-to-day as a SAHM. I don't care about fashion or designer names, but I do want the best possible quality. It doesn't have to be new, and I'd like it to be black. Any ideas?
