To commemorate its newly-minted relationship with Canada, Nordstrom goes commando. A Commando-brand crystal thong, that is.Ok, you have my attention. What’s going on, Nordstrom? Turns out they’re giving the girls a great fit in the name of supporting breast cancer. Certified fitters are available for appointments all day October 3 and 4, with two bucks from every bra bought going to Rethink Breast Cancer. Nordstrom and participating brands (including Betsey Johnson, Spanx and Hanky Panky) will pony up $5,000 minimum. Like a little music with your lingerie? The DJ starts spinning tomorrow night at 5:00.
