Maria hits an ace with Baby-doll nighties and they have become a craze at this year's Australian Open.
With the likes of Maria Sharapova, Karolina Sprem, and Maria Kirilenko sporting them on court, the fans are rushing to grab one off court.
While Sharapova and Sprem wear powder blue and lavender dresses respectively, Kirilenko raised the bar with a ruffled pale pink dress designed by Stella McCartney.
Kirilenko paired her nightie with a flourescent orange sports bra and undershorts
The 18-year-old Russian beauty, Maria, described her dress as 'empire line'.
The nightie is also described as the maternity dress, ironically, with the baby-boom making news in the West.
Serena Williams, who sports a new fashion look at almost every event, has amazingly adopted a sober look and seems to have taken the back seat this year.
Sharapova says that she has tremendous interest in fashion and wants to explore it as an alternative field after tennis.
