1. The Flash (2014 TV series' fourth suit)
Fourth time was the charm for The Flash as it finally managed to produce a suit that was nothing short of perfection.
The thing that made The Flash season 6's suit so special was that it was a different look from all of the previous suits, and yet the most comic-accurate of them all. It was built out of the season 5 suit, taking what didn't work with that one and improving upon that; that meant adding more padding, some awesome yellow accents to even out all that red, and most important of all, a chinstrap. Not only had it restored the character's signature look from the first three seasons, it enhanced what it had, making more with less.
For years, we wondered how The Flash's suit could be adapted into live-action properly. This suit is the perfect example of how to do it. It's simple and effective, and that's what separates it from the DCEU suits, which tried to look too edgy and ended up making a sleek speedster look a little too bulky.
The Flash TV series has produced multiple beloved suits over the course of its run and no matter which one you prefer, there is no denying that it has gifted us with the definitive look for The Flash - one that has defined the character for a whole generation, and for the generations to come.
