Probably hard to tease apart, but I wonder if the "dying your hair" part matters as much as the "dressing more hip" part. Someone that looks like they're dressing well and have a sense of style is likely to innately have a better first impression than if you look like you're an extra in a sitcom. It'll help you stick out in people's minds, for better or worse, and shows at least some level of caring about the position.
I'm a younger guy, but I know I try to pick my outfit carefully when going for an interview. I don't have a totally different interview wardrobe or anything, but I pay a little more attention to matching colors and generally looking more put-together.
You may not even need to get your kids to dress you - just find a friend your age who cares about fashion some to help. Even if you think you dress well, having someone else check you over or make small suggestions can help.
