Here's the ever-elegant Princess Charlene of Monaco on her way in to the Dior Haute Couture show in Paris over the weekend. You'll notice, of course, that the princess is carrying a black quilted Dior Lady Dior Tote. Dior doesn't sell its bags online anymore, but you can browse the many variations of the Lady Dior (mink, python, and croc, oh my!) and find out where to buy one in-store at Dior.com
In the music world, wearing a band tee to see that same band is considered super lame, but in the fashion world, you should absolutely carry a Dior bag to a Dior runway show. It's de rigueur. Heck, you can even pair it with your Dior jumpsuit and Dior cape. There's no such thing as overkill when it comes to celebrating haute couture.
