Calvin Klein sizing guide: Find your fit | OPUMO Magazine

Calvin Klein is the brand that almost single-handedly invented the idea of designer clothing in the 1980s. The label today is the very epitome of low-key, high-end all-American style. These are pieces that almost define quiet elegance, with fabric and cut always at the forefront. The style is just this side of preppy, a fashion statement that’s almost not a statement at all. All of this is the result of the genius of the brand’s eponymous founder, who for many years retained a post as creative director of the visionary label he founded.

The young Calvin Klein began with a range of jeans in the late 1960s and opened his first shop in 1970. The rise of his brand hit a real moment. Within just a few years, he’d appeared on the cover of American Vogue magazine and was lauded with the first of three consecutive American Fashion Critics’ Awards. Klein expanded, with huge success, into men’s underwear and gender-free fragrance, this last being a real revolution at the time.

Calvin Klein sizing notes

  • Calvin Klein pieces generally fit to your usual size. The caveat is – as always – to check the sizing conventions that you are used to against Calvin Klein’s own sizing.
  • In our sizing chart, we’ve included UK and US sizing as well as EU sizes, to help you to find the perfect fit.
  • If in doubt, however, on any individual piece, why not consider ordering two, to find your personal Calvin Klein size?
