Just ordered my very first pair of Aquazzuras! Got the dolce vita heel in black from Saks for $300 off! I used their size calculator and it said it order a 9.5. I'm a 9 in designers like Cole Haan and Sam Edelman, but a 10 (40) in Jimmy Choos and Louboutin. Im second guessing ordering 39.5 and am wondering if I should grab the 40 while it's still available??
