Off-the-wall fashion and decor shop, is perhaps best described as the antithesis of Marks and Spencers, which - unless you’re shopping for Granny’s christmas present - can only be a good thing. Find everything that you just can’t get in your small town shopping malls and highstreet fashion stores: from vintage coats to fancy-dress outfits, funky 1940s furniture and fittings, and even a splash of light fetish (this is Berlin after all!). Waahnsinn is well worth a perusal, even if you’re too boring and conventional to buy anything.
