id: what is anastasija sevastova wearing?

Qualifier Anastasija Sevastova is through to the quarterfinals of this week’s China Open after Nadia Petrova withdrew because of injury. Must be a welcome respite for the Latvian — she played three-setters both in upsets of both Sam Stosur and Dominika Cibulkova. Unfortunately, her next opponent is hometown fave Li Na. See the rest of the draw here.

Teachable moment: We first saw Sevastova at the 2010 US Open, where she lost in the first round to Regina Kulikova, and snapped these pics of her dress. Can anyone out there ID the brand for us?
