Now I know there's a 90's revival etc, but when I was out shopping this morning, metallic mules similar to the link below were all over the place. Lots of knotted ones too. If you like em, fine, but I swear these are almost identical to the ones my gran used to wear when she was going on holiday to Benidorm about 25 years ago. Just about everything you see over the years has been here before one way or another, but I will always see my lovely gran in these shoes, tottering off for a game of Bingo!
