Gap sleeveless top with silver bib type decor

Gap sleeveless top in a blue and off white diamond medallion pattern. Has a silver decorated neck. It is not beaded. Lightweight and can be dressed up or down. Small keyhole in the back. No rips, stains or other problems. The last picture shows that the ribbon seems to be off track a tiny bit. I’ve never even noticed until I looked closely to take pictures. Size small.
