Moana Bikini NWOT Coco Amber & Karly Bow Runch Size S

Purchased brand new from another girl, she had never worn, only tried on and the same for me. Top was missing size tag but I was told she purchased a small from Moana. When I lay it flat on my other coco top it seems bigger so top might be a medium (if anyone knows what the measurements are for a medium coco top I can definitely check!) Either way it doesn’t fit me and I’m 34DD. Very disappointed because this sunflower on baby blue print is gorgeous.
