The bum bag. I never thought I'd see the day when I actually owned and wore one (too many memories of dodgy tourist outfits when holidaying in France in the '90s) but I'm a fully fledged convert. This leather bum bag (or belt bag as I believe it's now called) is now one of my favourite accessories, thanks to its clean shape and the ability it gives me to go completely hands-free, just carrying the necessities.
