This is an Omega Slip bikini from the German luxury brand Olaf Benz. The material is soft polyamide/Lycra, providing a smooth and comfortable fit! The color is yellow, and the size is indicated as S, but it's slightly larger, equivalent to a Japanese SM size. It's new and unused. I also have other items from EGDE for sale.
