Model couples also star in the brand's new jewelry and watch ads, which suggest we live in the now. Get it?

Ever come across an old photo of your mom--you know, a photo from before you even existed--and thought, "Damn, my mom looks good" and then "OMG I want that whole outfit"? Piper Weiss did, so she started a blog called My Mom the Style Icon where she posts photos of stylish moms that date from the 1920s through the 1980s, tells the stories of the moms in the photos, and offers up hilarious commentary on their outfits. That blog is now a book, and last night Coach threw a party to celebrate its release--just in time for mother's day. (Seriously, buy it now for your mom). True to her mom-style obsession, Weiss, who by day is an editor at Yahoo! Shine (you should read her stuff there because it's hilarious), wore a vintage Pierre Cardin dress that was her mom's in the 70s that she gave what she calls a "a shoulder pad-ectomy" and had shortened. Mama Weiss, the inspiration for the book, was there too, looking stylish as ever. There are exceptions to every rule, but it seems style is more often than not passed down from mothers to child. So we brainstormed with Weiss to come up with the ten of the most fashionable mother and daughter pairs (and one mother-son pair), and she offered her two cents on each stylish duo. What other stylish mother daughter pairs did we leave off?
