Nudists, people who like running around in their underwear and blow-up dolls enthusiasts could find themselves in hot financial waters in the Costa del Sol.
The Spanish region's government has announced its intention to get even tougher on stag and hen parties.
Anyone getting naked in the street, wearing just underwear or carrying any sort of object which represents a sex toy or private parts will face a fine.
Malaga already has strict laws in place, including fines for using megaphones or general unruly behaviour, as well as drinking in the street.
Some pubs and clubs even have a total ban on stag or hen parties and refuse to let revellers in.
Now, Malaga city council has gone one step further in its tough stance.
Yesterday, the authority approved new clauses to its existing laws.
In future, anyone in a stag or hen party found naked in the street or stripped down to their undies will be fined €750 (£688).
The same penalty will apply to anyone who carries an object, doll or inflatable which looks like a private body part or of any sexual nature.
Police are able to dish out warnings before they doll out the financial penalty.
In a statement, Malaga City Council explains that its objective is to "put a stop to some uncivil behaviour that may disturb coexistence among residents."
"The proliferation in recent years of certain behaviours associated with nudism, the use of underwear or erotic content in public spaces advises giving the municipality a new regulation," said the authority.
"The ultimate goal is to preserve public space as a place for meeting, coexistence and civility, in which all people can freely carry out their activities of free movement, leisure and recreation, with full respect for others and for the plurality of expression."
Over the last year a number of Spanish regions have introduced rule designed to control the behaviour of tourists.
At the start of summer 2022 a new law was brought in in Barcelona, which makes its 10 beaches smoking-free.
Anyone caught smoking a cigarette will face a a 30 euro fine (approximately £25).
Barcelona isn't the only popular holiday spot where the smoking ban applies - the Canary Islands and Balearics also have similar rules in place.
For example, smoking is banned in Majorca such as Santa Ponsa, La Romana (Paguera) and Carregador (Palmanova).
