Thanks for your help. FYI it's not Erdem http://www.peoplestylewatch.com/people/stylewatch/gallery/0,,20616361,00.html#21194639
It is, actually. I couldn't find what season it's from but I remember seeing the exact print on a tank top on eBay recently. Here's the link for the top on eBay: http://www.ebay.co.uk/itm/Erdem-Silk-Tank-Top-Size-10-/271032633728?pt=UK_Women_s_Tops_Shirts&hash=item3f1acdc980#ht_500wt_1193 My apologies if I'm not allowed to post it.
