Waist belt and clothing system

Abstract

A waist belt for trousers, skirts and similar garments that are equipped with belt loops is formed from a band flat material that includes a central straight portion that has a predetermined length and covers a wearer's back. The central straight portion is orthogonal to a central symmetry plane. First and second terminal straight portions have a predetermined length and include respective buckle elements for mutual removable connection. The terminal straight portions are arranged orthogonal to a same terminal symmetry plane. First and second curved portions are symmetrically arranged with respect to the central portion and connect the central straight portion to the first and second terminal straight portions, respectively. The curved portions are configured to keep the terminal and central symmetry planes at a distance from each other between 3.2 and 20 cm. The belt enables a related system and a modified garment configured to fit the belt.
