Billabong bikini bottoms in a timeless silhouette. Billabong Feelin’ Peaceful bikini bottoms designed with a lightly scooped low-rise waistband and cheeky rear coverage. Complete with an allover floral print. An icon in the surf industry for decades, Australian brand Billabong got its start when founder Gordon Merchant started producing board shorts by hand in 1973. Now, they maintain a prominent presence among surfers, while also creating swimwear that looks just as good lounging on the beach as it does riding the waves.
