I've bought a pair of chanel shoes half a size too small, I've already worn them, thinking they were just a bit snug. But I've realised they are just too uncomfortable. These are my first Chanel shoes, but I've had other leather shoes which stretch or seem to have more give with a bit of wear. Can someone with more experience tell me whether these will stretch a bit? Or am i destined to have to wear them just to sit down events?!
