We‚Äôre definitely not flip flopping over how much we‚Äôd like to get our hands on a pair of these. And while designer flip flops may not seem like the most practical thing to traipse around in at the beach but these Havaianas are one of a kind pieces of art and benefit a good cause. In celebration of Selfridges‚Äôs Havaianas customization pop up shop, celebrities and designers like Manolo Blahnik, Paul Smith, Matthew Williamson, and Naomi Campbell have all tailored their own pair of the Brazilian flip-flop. Selfridges is auctioning them off to provide support and care for children with cancer and their families. Take a look at the one-of-a-kind flippers here.
