Mary wore a mermaid costume with a red curly wig which was a contrast to the other girls.
One fan took to Twitter to say: "Why oh why did Mary just come out as Ariel the little mermaid!? #LoveIsland"
Another said: "Love island just done Mary dirty she looks like she’s about to go to the school disco #LoveIsland "
A third person took to Twitter to say: "someone get Mary out of that costume right now #LoveIsland"
Fans also weren't happy with Jake Cornish's outfit when he came out in a Viking costume.
The girl to make the most boys' hearts raise was Millie Court then Liam Reardon jokingly told her to 'burn' her outfit.
The girls managed to raise the boys' heart rate the most collectively rather than the boys raising the girls'.
