These shoes are absolutely gorgeous! I planned to wear them for a formal wedding in Texas. Tried them on as soon as they arrived in shipping. They were snug, but I could walk around the house and I was quite excited because they're so sparkly! Packed them in my suitcase, flew to Texas. Once I got to my hotel, I found that my feet had swollen a bit with flying, but then when I tried the shoes on, I couldn't even get my feet into them at all. I even slept in a cold room with my feet propped up all night. No luck. All of my other shoes still fit. For the wedding, I had to race out and buy another pair of shoes...same size, definitely not as beautiful. I tried the shoes back on when I got back home, but they STILL don't fit. It sounds strange, but I wonder if they shrunk during my flight. Anyway, my word of warning is buy the next size up...especially in the summer.
