The trend is growing on social media app TikTok with users donning cardigans and powdering their hair white to pass off as old people.

A video with over 2 million views shows a girl in a grey wig and Halloween costume mask before tearing off the disguise as she gets the booze.

The ''creative'' trend has proved popular with other TikTok users and many have vowed to try it for themselves.

One person commented: ''These are getting all the more legit looking and I'm here for it.''

Another user added: ''Omggg if I was in high school with this kind of innovation I could not be stopped!!''
