I've tried on the first and last pair, and IMO, the last one would be my choice. I loved the first one, but it's made with a light colored fabric, which can get really dirty and hard to clean, esp with crystals on them...they are beautiful though. Also, they were cut a little narrow, so someone like me with medium wide feet will start feeling the pinch after wearing it for awhile.
The middle pair I don't think can be worn with many outfits and are harder to take through the seasons.
The last pair is great b/c it has the fanciness of an evening shoe, but due to its simplicity, can be worn either way, with a party dress, or with jeans. They are a totally updated classic. Neutral crystals match everyting...you can't go wrong.
