In chronological order:
Ultimate Warrior (WrestleMania VI)
In addition to having one of the best physiques in WWE history, Warrior also possessed one of the most unique attires. The orange tights and knee pads stand out so much that they draw attention away from the green boots. The multi-coloured wrist bands and tassels add to his already-overwhelming charisma. The face paint and chest paint create an aura of mystery about the character, which separates him from the rest of the roster.
Shawn Michaels (WrestleMania XIV)
This is easily Shawn's best attire in his career. The red tights and gloves contrast perfectly against the black and white boots. The design of the DX logo on the red is multi-coloured, giving a look similar to a Hawaiian theme. The silver chaps and vest look very bling bling, adding to the reputation of being a showman.
Kurt Angle (WrestleMania XIX)
The red, white and blue design gives Kurt the look of a superhero, only without the goofiness of some of his other designs. This one is kept simple, with blue as the primary colour. The red boots with the white laces stand out, but keep in line with the American flag design.
Randy Orton (Vengeance 2004)
The red tights contrast against Randy's other accessories nicely, while the white wrist tape and black elbow pads give the appearance of a ring technician. I also like how the patterns on the tights are similar to his tattoos. The attire is perfectly assembled to compliment Orton's physique.
