Yes, in towns like Positano and Sorrento, you could face fines for walking around bare-chested or in swimwear outside of the beach areas. Swimwear is fine on the beach, but make sure to cover up when exploring the towns. Additionally, in Cinque Terre, proper footwear is essential for hiking the coastal paths. Flip flops and sandals can result in fines, so sturdy shoes are a must.
