Newquay's decision to ban mankinis has significantly reduced anti-social behaviour in the town, police and community leaders said.
Officers in the Cornish seaside resort brought in the ban as part of a drive to help shed its "Wild West" image as a haven for stag and hen parties.
And they say their crackdown on excess drinking, public disorder and the wearing of inappropriate clothing, such as mankinis, has helped cut crime in the town.
Inspector Dave Meredith said: "People expected to come to Newquay to drink a lot, behave irresponsibly, a lot of really young people came to Newquay and knew they had a good chance of getting drunk.
"Certainly we have clamped down on that and the image of Newquay now has certainly curtailed some of that."
In 2009 locals joined protest marches to "take back their town" from the grip of anti-social revellers.
Town mayor Dave Sleeman said: "I remember back in the 2000s you couldn't walk the streets on a Saturday without seeing someone wearing a mankini or what have you.
"But now they're not allowed in Newquay. The police will tell them to go home and get changed if they see them wearing one, and the guest houses and camp sites are pretty good at warning their guests about what's acceptable."
