Mateus celebrated 30 years of giving people the opportunity to express their style and mood for both everyday and festive occasions! The anniversary was celebrated with an exclusive exhibition at NK Department store, created by the Golden Egg-winning creative studio Ray Atelier. During the evening, guests were treated to an exclusive performance by internationally acclaimed Swedish artist Seinabo Sey, as well as food from award-winning Restaurant AG. Grand Relations’ assignment was to develop the concept for the celebration and the event. This included planning, press releases, invitations, guest lists, rsvp, and production and implementation.
