Sometimes, the important questions need to be asked. And if you were watching Married At First Sight on Wednesday night, we bet this one popped into your head, too:

How – wait, no, WHY – did Sarah apply her fake tan like that?

It was pre-dinner party and the faux-marriage fanatic decided to bronze up with her fancy dress already on.

You go Sarah Roza, you good thing. Image: Channel 9.

So fast and loose. So... un-beautician-ly. And yet, Sarah walked away from her bathroom vanity looking flawless and bronzed and glowy.

We would have liked to see what the male contestants' white shirts looked like after giving her a 'hello' hug, but who cares about them. WE CARE ABOUT THE TAN.

Judging by Twitter, you guys did too:

I almost had a heart attack watching reality TV! Girl no!! Dont go putting fake tan on when your beautiful gown (that needs dry cleaning) is on your body! That shit stains! #MAFS

Forget the dinner party drama! What tan did Sarah smear on with that mitt? It looks amazing ???? #MAFS

#MAFS ok everyone - what is that fake tan product Sarah was putting on? Do you just rub it on before you go out and leave it on?

I love you Sarah but who applies fake tan when they're already dressed? #MAFS #marriedAu

Who puts fake tan whilst wearing an evening dress? ???? #AskingForAFriend #MAFS #mafsau @MarriedAU

So, do we have answers?

It's safe to say Sarah was using some instant tan - we're just not so used to seeing a woman apply it so brazenly (and immaculately) with her ball gown on.

Meanwhile, the people of Twitter suspect Sarah's perfect tan was the result of this miracle product... as they say, walk don't run:

St Tropez do a great one. Excellent for pasty legs! pic.twitter.com/AeGMd7QgBw
