Trousers should hang from the shoulders, not the waist. And when it comes to supporting one's trousers from the shoulders there is but one name to consider, in my opinion, and that is England's Albert Thurston. ASW carries only the best of the best, eschewing machine sewn models with black or brown leather in favor of hand stitched white ends.
The stock at the ASW store have covered ends by default, including the barathea models that must be special ordered from other suppliers. Barathea of course is for warm weather and boxcloth for cooler temperatures. The former have nickle adjustors and the latter brass.
In the photos, khaki barathea and maroon boxcloth, 1 1/2"(38mm) wide and offered in three sizes so the adjustors can be properly set below the ribs so as not to distract from your face.
