Barely worn swimsuit- size small- medium coverage!

Beautiful one piece is mint condition. Had this suit before kids and now top part doesn’t fit my mom chest lol. Beautiful deep purple/maroon color. So flattering. Open back! Comes from a smoke free/pet free home! I cut the tags and cannot remember the brand for the life of me. I bought from Marshall’s so I know it was a name brand. I kind of want to say Calvin Klein?!
