Lululemon isn't technically a golf clothing company, but one of the best female golfers in the world is now wearing their gear on the course. Lydia Ko became a Lululemon elite ambassador officially last month, and the LPGA Tour star discussed the new partnership last week at Hazeltine National during the KPMG Women's PGA Championship.

Though Lululemon doesn't have a 'golf' section on its website, Ko, who does yoga, says the fit makes more sense than you'd think.

"They're all about being mindful," Ko said of Lululemon. "I think that really plays into golf. It's not just a physical aspect but it's mental as well."

Ko's partnership contributes to the larger athletic trend in golf apparel. Fabrics are more performance-based than ever, and you can find ways to wear athletic gear you're comfortable in on the golf course. Just because a piece of athletic clothing you love isn't labeled golf clothing, doesn't mean you can't wear it on the course.

"It's great for golf," said Ko of Lululemon's support, "and for people who may not know a lot about golf but are huge yoga fans, maybe they could get into golf. I think the two play well together."

Here are some of the Lululemon outfits Ko has worn on-course lately—and how you can buy each piece.

During the first and third round of the Women's PGA Championship, Ko wore the Lululemon Breeze By Long Sleeve shirt over the Swiftly Speed Polo and On the Fly Jogger. Lululemon's offerings are refreshed often, here is what is still available and some similar looks to try out.
