Yahoo announced today that it has agreed to buy the social shopping site Polyvore.

The sale price was not announced. The deal is the most recent in a spree of more than 50 acquisitions by Yahoo since Melissa Mayer took the helm three years ago.

Polyvore will continue to offer its core service on a stand-alone basis. Much of the Polyvore staff will move over to Yahoo, including the CEO, Jess Lee.

Yahoo expects the acquisition to enhance its own consumer and advertiser offerings, namely its digital magazines. Some of the Polyvore social and e-commerce tools could be integrated with the Yahoo Style and Yahoo Beauty sites.

“When it comes to advertising, Polyvore’s technology will bring a proven native ad model, new compelling native ad formats, and strong advertising relationships with more than 350 retailers to Yahoo’s fast-growing native advertising platform, Yahoo Gemini,” Yahoo said in a statement announcing the deal.

At Polyvore, community members can arrange and display collages of clothing, or arrange coordinated pieces of home decor.

Polyvore’s investors include Goldman Sachs, DAG Ventures, Benchmark Capital, and Matrix Partners.
