If you are planning a trip to Italy for the summer holidays, then be careful not to go out in a bikini on the street.

The city of Sorrento has announced a bikini ban and tourists who break the rules will face fines of up to 500 euros. The rules also apply to male visitors walking around town topless.

However, you won't be fined if you're sitting by the pool or hanging out at a beach club. This is because the new measures apply when people are out on the streets of the city, whether walking to the shops or going to a restaurant.

The mayor of Sorrento, Massimo Coppola, announced the move, claiming holidaymakers going out in bikinis were causing locals to feel 'embarrassment and discomfort', the Times reports.

He added that those who walked in a bikini or topless were seen by most people "as opposed to the decorum and decency that characterizes civilized coexistence".

Sorrento is not the only holiday destination to have such a swimwear rule.

In Barcelona and Majorca, people can only wear bikinis on the beach, with fines of up to 300 euros in Barcelona and up to 600 euros in Majorca for those who don't respect the rules. Like Sorrento, this also applies to men walking topless.
