It was an exciting game, with both teams producing a 4-4 tie and lots of drama.

Wett’s wardrobe choice, however, offered plenty of fodder for discussion prior to the game.

Wett appeared to be wearing a top that supported both teams.

The Blues made up half of the team, while the Cityzens made up the other half.

It was a sin for football fans, who thought the gaffe was far worse than a half-and-half scarf.

“That is the most horrific shirt I have ever seen,” one fan said online.

Another said, “The state of that honestly doesn’t get much worse does it.”

“I thought there was nothing worse than a half-and-half scarf,” said a fourth. Pathetic!”

Wett has created a name for herself as a fighter on YouTube.

She recently defeated Alexia Grace in KSI’s Misfits Boxing competition.

Elle Brooke is the frontrunner to be her next opponent after she has defeated each of her first three opponents.
