There is no rest for fast-fashion retailer H&M. On the coattails of the über-successful collaboration with Lanvin this fall and the recent announcement of the first-ever blogger-designed line, the Swedish brand has proven that they have a knack for developing seriously stellar fashion alliances. The retail giant announced today that they would be teaming up with old school clog maker Swedish Hasbeens for a one-off collection. Tapping into the 70’s vibe that swept through the spring collections, H&M has created an exclusive line of wooden-soled clogs that are sure to become a wardrobe staple this season. The collection is slated to hit stores worldwide on April 20th.
