I'm in the market for patent leather Clichy 120s and am completely confused about the sizing. I read in the reference library that one of our TPFers bought a whole size up, but I believe it was for the 100. Then I read in the sizing thread that Clichy buyers should go 1/2 size up. I called around to a few boutiques and an SA told me to buy 1/2 size down since it's a 5" heel and that's what her other customers have been buying. Can someone please enlighten me on the most appropriate sizing to go for? I'm usually a size 36, I have a pair of patent leather decollete 100mm in 37 that fit fine with a heel liner and a foot pad for the ball of the foot, should I go with my decollete size?
