Don't know too many females who don't have a shoe obsession. Wear the most basic outfit and throw on the hottest shoes and your set. Shoes are the period that complete a sentence. I gasp for air sometimes when I see a pair that I just have to add to my collection.
Designers always try to re-invent designs and keep fashion fresh and new. Some do it in a wearable manner and some just blow our mind, LITERALLY!
