Trunk Clothiers was founded by Mats Klingberg in 2010, opening its original shop on Marylebone's Chiltern Street directly opposite where the Chiltern Firehouse would later open. A second location followed in March 2018, on Zurich's Dufourstrasse in the Seefeld district, sharing a space with the Monocle Shop and Café. Alongside brands like Alden, Barena, and Boglioli, it sells its own in-house Trunk label, with tailoring made in Italy and shirts and chinos made in Portugal.
