Waist straps typically adjust using multiple punched holes or an elastic/buckle design. Listings commonly include a fit range (examples given include 26" / 66 cm to 32" / 81.3 cm) and may also show larger ranges in centimeters (for example 88–102 cm / 34.6–40.2").
Dress belts are described as slim leather straps (about 1 1/8" wide) with a polished silver-tone buckle and a two-loop design for a neat, tailored finish.
Materials shown include genuine leather, bonded leather, polyurethane and other faux-leather materials, plus supporting components such as elastic and metal/alloy hardware.
Closures include buckle-style options (interlocking, pin/rectangle and tang-style buckles) for waist and dress belts, and silicone-ended attachments or silicone buckles on eyeglass straps.
Design details include decorative hardware (polished or silver-tone buckles, metal end tips and loops), multiple punch holes, tang-style buckles, two-loop constructions and decorative finishes such as floral embossing.
Eyeglass straps commonly use silicone ends or silicone buckles to secure frames, use durable alloy hardware, are lightweight, fit most eyeglasses and sunglasses, and are often around 25.2" long. Some models convert to a necklace by removing the silicone ends.
