The summer of music festivals continues, this time in Gdynia, a Polish port town on the coast of the Baltic Sea. The Open’er event was recently held there, one of the largest festivals in Europe, which attracts upward of 50,000 attendees. This year’s headliners included The Black Keys, Pearl Jam, Jack White and Faith No More, thus the fashion veered grungy with torn denim, flannel shirts and lots of black. Still, those ubiquitous festival standbys made appearances, too (flower crown, anyone?), as did, oddly, a panda and tiger suit. Anything goes in festival land.
