PIPER PRETTY: The Piper sandal from the Piper Sandal Company is a summertime classic, in our sweet-on-sandals opinion, but sometimes one wants to tweak a classic look just a smidge. Which is why we're glad that this company makes red and green and purple versions of its famous sandals. We're definitely looking at the purple Piper slip-ons for summer 2010. NEARLY FOUR DECADES AND COUNTING: They've been making the Piper since 1971. That's a solid backstory. A pair runs $119; get ordering details.
