Neiman Marcus black pattern triangle bikini top

Black. Neiman Marcus brand. Authentic. Triangle. Bikini top. There are two hooks to change the size. The loosest hook length is approx 27" across. The tag says size 10 but I would say it's a medium. I wear size small and medium and it's fits me just is a little big in the cup. I'm a 34 A if that helps when you see it on me. The swimsuit has a pattern on it in another shade of black thread. The pattern continues on the band and ties of the swimsuit top!!
