Purchased these along with ‘Beyond the Ocean’. Both in large size. This pair ‘Cactus’ is cut more generous than the other. Great fabric and style. Very comfortable. I purchased the large size as I typically wear size 32-33cm. Nice fit. Would prefer to have a bit more elastic/stretch in the fabric (maybe Lycra?) so that is a bit more hugging. I think if I had purchased the medium size they would be too tight. The large size are just giving a bit of bum cheek, but could do with a bit more fabric / stretch to cover a bubble butt. Great swimwear that is not mundane.
