That's right, it's not all pickled green tomato recipes, omega workshops and essential items for that all-important "Hamptons Packing List" on her lifestyle website.
The British actress has hired new CEO Lisa Gersh (the two were introduced by the infamous celeb fitness instructor Tracy Anderson) who will head up the new line of wardrobe staples.
This Goop-branded apparel is Gwyn taking a shot at doing it herself, though and the new range will also include home and beauty products. Clearly, she's had a few pointers from her designer bestie Stella McCartney.
"We've seen the mistakes out there," said Gersh in an interview with Reuters.
"We'll take small steps".
Plus there's collections with Stella McCartney and Diane von Furstenberg in the pipeline which are sure to go down with Gwyn's fash pack.
Roll on 2015, we say!
