Are you sure? to me it looks like one of the clay court season tops from this year.
I'm not sure it all I found it on their website and it was called the "Justine cap sleeved Competition shirt" - which is the line Justine wears. Also, her publicist stated she was going to be wearing a shade of blue at the AO.
I think that Adidas have the most beautiful outfits..I love Ana's and Dinara's dresses a lot....Masha's dress isn't so pretty to me, but what ever she wears she is beautiful in it..and Jelena's dress...no coment :P
