Glad you asked...
You can make your own custome suspenders at home. To make them you will need a measuring tape, elastic, fabric, suspender clips and a sewing machine. Check out this site for complete directions for making suspenders. http://www.ehow.com/how_5541683_make-pan...
Then again, this answer might help you...
Suspenders are essentially long pieces of elastic bands that are secured to trousers over the shoulders. The two straps are crossed in the back at the mid-point. Most use adjustable clips in the back and buttons in the front for security.
