You've heard of hiding in plain sight.
Well, a fashion designer has come up with a more colourful way for worried women to blend into a busy street to elude a pursuer.
We've had mini-skirts, skorts, pencils and midis. Now there's the vending machine skirt.
It's definitely not the real thing, but Aya Tsukioka's skirt doubles as a disguise to make the wearer look like a Coca Cola machine.
Aya Tsukioka's skirt aims to make the wearer look like a Coca Cola vending machine...Ms Tsukioka, 29, unveiled her design in Tokyo by claiming she hopes it will help ease women's fear of crime.
She lifted a flap on the skirt to expose a large sheet of cloth printed with the familiar bright red Coca Cola logo.
By unfolding the sheet and stepping to the side of the street, she showed how a woman walking alone could hide behind it to outfox a potential attacker.

The experimental clothes designer has already sold 20 of the £400 hand-sewn vending machine skirts and it hoping to market the design worldwide.
She says the idea was inspired by a trick used by Japanese ninja assassins, who cloaked themselves in black blankets so they couldn't be seen at night.

For children, she has a backpack that transforms into a fire hydrant.
While British women might prefer to take self-defence classes, Ms Tsukioka said: "It is just easier for Japanese to hide. Making a scene would be too embarrassing."
She admits that making the switch from skirt to vending machine might prove a little tricky "especially when your hands are shaking".
But she told the New York Times: "These ideas might strike foreigners as far-fetched, but in Japan, they can become reality."
