Game, set, match.

Looks like back-to-back Wimbledon champ Serena Williams has more than one reason to celebrate these days. The tennis star is also showing off her slimmed-down figure in a glamorous spread for the August issue of Harper's Bazaar.

Williams -- who rocked Burberry to celebrate her Wimbledon win -- poses in a chic white Eres one-piece that shows off her enviable frame, topped off with a classy Louise Brooks bob.

(Note to nude-hued panty-flashing Venus: This is how you do sexy.)

Photographer William Klein also captured the court queen in a gorgeous pale pink Fendi dress as she opened up about beauty and body image.

"Since I don't look like every other girl, it takes a while to be okay with that," Williams tells Harper's Bazaar. "To be different. But different is good.

"I feel so much sexier with short hair. I wanted to reach inside me and feel better. I don't want to hide behind a facade of hair."

And even though many gals would kill for her svelte physique, Williams -- who keeps trim through (um, tennis) Pilates, yoga, and "no dieting" -- admits that she hasn't always felt confident about her body.

"I was 23 when I realized that I wasn't Venus," she says.

"She's totally different. I'm super curvy. I have big boobs and this massive butt.

"She's tall and she's like a model and she fits everything. I was growing up, wanting to be her, wanting to look like her, and I was always fitting in her clothes, but then one day I couldn't.

"But it's fine. Now I'm obviously good, but it's a weird thing... To this day, I don't love my arms. People want more fit arms, but my arms are too fit. But I'm not complaining. They pay my bills."

No kidding. Even Michelle Obama would trade the Lincoln Bedroom for those guns.
