There is an even mix of plastic and metal frames, both materials come in a variety of different colors. I'm partial to the colored options, like the yellow-ish option below, or the darker lucite pair in the first picture. They are oddly only a few styles available on Jack Spade's website, so I would suggest visiting Selima's site, or stopping in to your nearest Jack Spade shop.
Prices range from $295-$325.
