For shoes that cost just $138.95, I think these Martinez Valero flats have a bit of a designer look to them. From the silk uppers and brooch detail to the cute slingback, they're proof that an evening shoe doesn't have to have a high heel, and the bright colour is very springlike, too. These also come in black and white, and are available from Endless.com.
