In Barcelona I fell in love with Pull&Bear. It feels like I bought the whole a/w collection, including this dress. I found it on our last day and it's really one of my favorite purchases. You should definitely check them out! They do have a online shop, and as far as I know a Shop in Vienna is planned.
If you like my knew Header, you should check out Angela's Blog the 3rd voice (click!). Her blog is one of my favorites and I made the Header according to her Tutorial.
I also changed the Layout a little bit, because I had some problems with the Quality of my pictures.
