Lorna De Vera 5 I love the shoes! I was skeptical to order at first because I didn't know how the sizing works but then I took the risk and it came. I'm a size 24 and I ordered the size 23.5~24.0cm just to be safe but then I saw that it is worn two ways and that is why the sizing chart is like that. Obviously 23.5cm is too small for my size and I can only wear the shoes on the second style shown in the picture, where the third strap is behind the ankle part, because the third strap just doesn't go pass the bridge of your feet. If you plan on wearing the shoes in the first style, like me, I suggest you go with the size bigger than your actual size. As for me, I ordered again but now it's in 24.0~24.5cm and it's coming! I am still keeping my first order. Over all it looks cute and I hope this helps with your purchase.Disclaimer: my suggestion is based on my feet. Obviously, every feet is built differently. This is just how I thought about how the sizing works.
