“Unicx” is the statement with which Aldabaldetreku, the Basque Country’s premier tailoring house, unveils its new 2026 collection. This name coherently expresses a philosophy built on two core ideas: to make each wearer feel truly unique (hence, unic, from the Spanish word único, meaning “unique”) and to create ensembles designed for everyone (the letter x in Spain is used to refer to people of all types and genders).
Fashion is returning to the roots of classic tailoring, even as the craft evolves with the year’s most notable trends: double-breasted suits, relaxed fitting male styles, and the timeless pinstripe. Aldabaldetreku’s latest collection showcases a refined selection of these styles, featuring pieces from esteemed houses such as Etiem and Ramón Sanjurjo, crafted from the finest pure fabrics sourced from Italy, the United Kingdom, and Spain.
For evening celebrations and formal night events, the tuxedo once again takes center stage — particularly in its most elegant variations with shawl lapels. Each year, this spirit of sophistication finds its way to the San Sebastián International Film Festival, as Aldabaldetreku dresses leading actors and actresses from across Spain for their red-carpet appearances.
For more informal occasions when a suit is not required, the house’s San Sebastián boutique offers a casualwear section featuring Basque and international brands such as Tantä, Batela, and Lacoste, with a focus on the timeless, classic lines of each label. With this thoughtful approach, Aldabaldetreku has succeeded in dressing both locals and visitors with impeccable style through every moment of their day: at work, at weddings, at leisure, and in life’s most “Unicx” celebrations.
