Navy & Red Reversible Bikini Top

Like new condition string bikini top. Sold as a size medium, but fit me as a 32D. I bought it at a department store but cut out the enormous tag and so I am unsure of the brand. I think it might be Nautica, it's nice quality. The cups are adjustable on the bottom string. Wore once last summer, but my chest grew and now it doesn't fit anymore. Sold alone, no bottom.
