We remember a red and white gingham outfit we used to dress Barbie in when she had a picnic date with Ken (Ken wore shorts and a golf shirt). Fast forward 20 years and we're craving a little bit of gingham in our closet for spring.     Christopher Kane put a fresh spin on gingham for Spring 2010. Whether his gingham dresses featured cut away seams or sheer overlays, his message was clear: gingham is good for more than just a picnic.     We've fallen for H&M's version of the gingham dress. At less than $50 a pop, we can think of many a spring time event that would require such an adorable ensemble.
