Here at OK! magazine, we're huge Zara fans. So when we saw a TikTok video revealing the secret tip on how to guess your size, particularly as the changing rooms have been shut for almost a year, we couldn't quite believe our eyes.
Zara sizes have never been their strong point, but their fashion forward styles and flattering fabrics certainly make up for it.
Earlier this month, TikTok account Officially_ Outfits claimed that there is a secret clothing symbol on the price tags indicating how it fits - and it totally makes sense.
The shopping hack TikTok star claims that a grey square means you should choose your normal size, while a triangle means that you should size up.

The TikTok video went viral and racked up over 460,000 views with hundreds of Zara fans commenting on how good this little hack is.
A fellow TikTok user, @cooookiemonster210, supported the video and explained how a member of staff once told her this trick while she was purchasing some clothes.
They explained: "The lady working on the register said anything with a triangle on it means you need to size up as their clothes are fitted based off European sizes".

However Kym Marsh 's stylist Martine Alexander decided to investigate herself to see if the rumours were actually true.
Martine said: "I went into Zara and asked one of the members of the team, 'Can you dispel the myth?' and they just said 'actually it just relates to the different sections in Zara'.

"So it's the different brands, whether it's Zara woman, Zara basic or Zara TRF. TRF comes up slightly smaller, Zara woman does come up a little on the generous/ true to size, and Zara basic is just basic and is true to size.
"Although we all know that Zara do have their moments where sizes are all out of sorts. So I just wanted to let everyone know that that was the truth behind the Tik Tok video."
So there you have it! The Zara size mystery has been solved and thankfully the changing rooms are now back open so we can try before we buy!
