Upon reconsideration, after watching the video, it is a young couple with newborn twins. So I wish them well. Maybe use the ties to make those things that holds babies in front of the wearer or a nice shoulder holster for a very light firearm. Great idea to recycle the dime a dozen old ties, but I'm not sure as braces looks good. Perhaps as real suspenders, you know, on the legs. Or unfold them and sew a few together to make really snazzy bandanas. Or some cool hat bands. Or add some elastic and make those arm things the guy in the photo is wearing. Roll them into snappy shoe laces?
But what do I know. I'm old. Maybe this can be positioned as an anti-establishment statement and will catch on with the subversives within the suit wearing crowd or perhaps it will be a hit with the non-suit wearing crowd.
