Guessing Vika will only wear one/two of the colours and the others may be what Lisicki/Safarova will wear. From a few websites I've seen Vika will wear the peach version, not sure if she'll be wearing one of the other colours too.
Updated the first post, I don't know how long it's been
Some new stuff. Not sure if it's for the end of the year [Linz/YEC] or 2013. She might not wear any of these outfits at all because last year she was wearing the same outfit for Beijing/Luxembourg and Sydney. But I remember in 2010 she got a new outfit (or at least different colour) outfit for YEC so who knows.
Anyway, here is the new stuff:
Skirt (other colours too):
According to tennis-point:
The Graphic Knit Tank is a highlight of the new collection and is at the WTA Finals worn 2012 in White by Julia Goerges and gray-green of Victoria Azarenka.
This is the same website that said she would wear the peach/orange top for the clay season but she ended up wearing purple so can't say she'll definitely wear that. Tbh, it doesn't really matter what colour she wears, just hopes she gets to debut a new outfit this time round.
