This trick to red carpet boobs is not for the fainthearted.

Ever wondered how all the boobs on the red carpet seem to defy gravity and just… be?

We finally know the secret, but it’s not for the fainthearted.

You’ll only need one thing but there’s nothing delicate about it… gaffer tape. Yep, the same multi-purpose hardware item you use around your house.

Listen: Sorry boobs, Vogue has decided you are out of style. Post continues after audio.

Just whip your top off, tape away and bam – gravity’s got no chance .

The trick was first brought to our attention by Kim Kardashian last year and it’s a staple styling trick of the red carpet for serious cleavage.

“You tape them up so they are super lifted. I’ve used everything from duct tape to packing tape to masking tape and I think that the best I found is gaffer’s tape,” she revealed on her app.

While it may work, given the worst part is having to remove it from your skin, we’d say proceed at your own peril.
