On the grand stage of WrestleMania, many wrestlers are prone to pull out every stop in order to make it memorable. This also extends into the fashion of the night. Much like how movie stars will dress up for the Oscars, wrestlers pull out elaborate costumes for WrestleMania that act like their version of a wedding dress: wear it once and be remembered for wearing it.
A lot of different attires at WrestleMania are remembered positively. For instance, the entire toga and Roman coliseum feel for WrestleMania IX went over very favorably. Also, pretty much any clothing worn by women at the event over the years sticks out in people's minds, mainly for the lack of actual clothing in certain instances.
But just as there are the best dressed, there are also many who are the worst dressed. There are times, like HHH's attire here from WrestleMania 22, that just kind of makes you scratch your head. Was this a cool entrance? Absolutely. Did it make sense that he was wearing so much fur and hold a phony toy hammer? Nope. John Cena's mobster-style entrance that happened a minute later was no better, but neither fall onto the top 10.
