"Splurge on Fusion Fashion Noventa Grados has been a stalwart in San Sebastián 's haute couture scene for longer than any of the other 'modern' fashion boutiques. In the heart of the old town, it prides itself on an ever-changing, boundary-pushing shop display that proudly announces the new arrivals from the likes of Balenciaga, Marc Jacobs, Proenza Schouler, and Stella McCartney. When you enter the boutique, however, you pass first through a hair salon (one of the best in the city). Then you'll glide through a section of makeup, perfumes, and sometimes even art before you get to the stairs that take you down to the designers. Keep your eyes and ears open in Noventa Grados as there's always something to discover, both material and ephemeral: they often host hip cultural events within the store."
