You already love shopping at LF for its indie-chic sartorial offerings. This Saturday you can love it extra, because each of LF’s stores across the country is donating 10 percent of your entire purchase to the Breast Cancer Research Foundation. Plus, LF will match your donation and enter you in a contest to win a $250 gift certificate. So if you’re in San Francisco, Los Angeles, New York, Miami, Boston or Dallas this weekend, hit an LF location, get your summer music fest outfits in order, and feel good about supporting breast cancer research. Happily, I’ll be in L.A. this weekend for the Lucky FABB blogger confernce. See you on S. Robertson!
