A German company has created a bikini that dissolves when worn in water.

The Get Naked Bikini, which is billed as the perfect revenge gift for bad break-ups, is a black swimsuit that looks, feels and fits like a real bikini. The only difference is it’s made from a material that completely melts away after a few seconds in water.

However, the bikini has upset women’s rights groups, with one campaigner, Rosmarie Zapfl, saying, “It is an absolute insult to women that this has been invented.”
