IS it a bra or is it a bikini?

We're not entirely sure. But it's certainly teeny tiny, and our very own Miranda Kerr is wearing it.

The Aussie beauty posed in the barely-there item for fashion publication i-D magazine to celebrate the launch of their new digital venture.

The bikini first became famous when British model Stella Tennant wore it on the runway back in 1996, instantly boosting her to supermodel status.

Kerr, 30, was joined by model of the moment Cara Delevingne, Lara Stone, Natalia Vodianova, Joan Smalls, Lindsey Wixson and 20 other models for a short film covering the mag's favourite slogans over 33 years of covers, the A to Z of Wink.

Unsurprisingly, Miranda was B for 'Babewatch'.
