If you thought Hilary Swank was the kind of serious two time Oscar-winning actress who wouldn’t become the latest in a never ending chain of celebs to launch a clothing line, think again.

Hilary Swank is developing a clothing line, WWD is reporting. Swank is working with DMA Designers Management Agency, the same agency that arranged the collaboration between Amar’e Stoudemire and Rachel Roy, to develop a concept for her collection.

Swank’s line will reportedly have an athletic bent, given her gymnast background. “Our platform is a contemporary, outdoor, athleisure brand,” DMA co-founder Marc Beckman told WWD.

While this news might seem a little out of left field, given that Swank isn’t an actress who is particularly known for her style (though we’ll never forget the Guy Laroche she wore when she won the Oscar in 2005), there was that head-scratching item last month that she is developing a fashion game show for the CW. Two years ago she signed on to produce a movie version of Falling Out of Fashion, a novel by Jane Pratt’s former executive assistant Karen Yampolsky. We’ve yet to see anything come out of that deal yet but the title is listed in IMDB for 2011. And then let’s also not forget that she’s buds with Marc Jacobs and has been known to work in his West Village store just for kicks. So maybe Swank is more of a fashionista than we thought.

Lest you thought Hil was going it alone, DMA and Swank are interviewing designers to partner with for the collection. We’re thinking someone young with sporty edge–like Prabal Gurung, Adam Lippes or Lynn Devon–would be a good fit. Who do you think she should team up with?
