My purses have to be big because I carry a lot of stuff. I buy one when I win or play well, so they're sentimental to me (Here, the Muse bag by Yves Saint Laurent).$1,395ysl.com
Taylormade r7 7-Iron
I do drills with my 7-iron, but it's not fair to favor one club over the others. If you're good to them, they'll be good to you.$105taylormadegolf.com
Peanut Butter & Jelly
I always eat PB&J sandwiches on the course. I've carried one in my bag, ever since I was in junior golf.
David Yurman Pendant
I like to wear jewelry when I play. David Yurman is so classic and beautiful. Morgan Pressel gave me this Petite Albion pendant with garnet and diamonds for my 21st birthday.$590davidyurman.com
BMW M6 Coupe
I went shopping for a new car a year ago and considered a few, but I'm so happy I decided on the BMW. It's my favorite thing.$99,100bmw.com
Samsung nv10 camera
I am obsessed with taking pictures. My Samsung is so cool -- black, with 10.1 megapixels. It was awesome to have it handy when I met Justin Timberlake at St Andrews earlier this year. He's my favorite musician.$300samsungcamerausa.com
Biographies
Right now I'm reading tennis star James Blake's book, Breaking Back. His story is so inspirational.$26barnesandnoble.com
Bronzer
I'm fair and I always wear sunscreen, so bronzer gives me the extra color I need (Here, Hoola bronzer).$28benefitcosmetics.com
Sundog Eyewear
I have my own sunglasses collection. I designed four styles that are performance-based yet fashionable. I usually wear the Strive, but at the Solheim Cup, the team got commemorative shades Sundog made for us.$60-$70sundogeyewear.com
Christian Louboutin Shoes
I always travel with heels—they're the best part of any outfit (Here, the Pigalle Graffiti pump).$675neimanmarcus.com
My Style Icon
I love the way Reese Witherspoon dresses and carries herself. I'm a big fan of her movies.
