Check out the 1994 Kit for Team Castorama. I think this is possibly the most horrifying kit I have ever seen. Luckily, Laurent Brochard is sporting a mullet which allows him to pull it off.
Take a closer look though. Is the top supposed to look like some kind of Frankenstein bib overalls or something?
Submit me pics of what you consider to be the most horrifying kit you have ever seen and I might just throw a Garmin Chipotle pb H30 water bottle at you (literally.)
