I just received my Tory Burch Reva's in the mail today, I ordered the metallic gold in a 8.5. I ended up going to the store to try on a pair, because I was so confused as to what size I should get. I really recommend trying them on before you order them if you are able to. I wear between a 8 and a 9 depending on the shoe. In the regular leather, the 8.5 fit perfectly, but in the pebbled leather I needed a size 9. Even though they have the elasticized back, I still feel like they are pretty true to size. I would suggest getting a half size bigger than you would normally wear and that's even what the girl from Toryburch.com said. They are amazing shoes, high quality, very comfortable. I'm extremely satisfied with them.
