Vintage early 50's swimsuit Striking Black and White

Vintage Black and White V neckline swimsuit. Not sure of brand the tag has been cut out but the quality is excellent and is in great shape. It was my moms and she wore a size 10-12. The unique thing is the straps are adjustable to 2 different lenghts with buttons. The bust is line with cotton, the fabric is a hearty weave but not scratchy at all.
