Anna Sui Spring/Summer 2010 Shoe Collection. Anna Sui was all over the gladiator style for her spring summer collection and even played with the use of butterflies. That was pretty clever of her to use butterflies in her designs since when it comes to spring people do tend to think of beautiful butterflies. Her collection was also filled with bright, vibrant colors perfect for the summer and spring season. Plus lots not forget her use of metallics, looks like that's a sure hit this spring in handbags and in footwear.
