Caroline Wozniacki “This is Me” new Underwear collection

Judging by her recent dip in form, she might have been advised to keep her mind firmly focused on winning Wimbledon.

But tennis star Caroline Wozniacki, who has slipped from world No 1 to seventh this year, has taken time away from the baseline to launch her new lingerie line instead.

The 21-year-old Dane, who is dating golfer Rory McIlroy, promoted her underwear range, called This Is Me, on Twitter.

Caroline describes the collection as 'A feminine lifestyle/leisure underwear collection for the girl that wants the good looks from fashion, a perfect fit for her body, and a quality that’s hard to beat'.

She has an impressive list of endorsement deals including Adidas, Yonex, Sony and Proactiv.
