Vintage Green Belt with Gold Buckle - Small

Thrifted this piece a while back but haven’t found the right outfit for it. It’s a beautiful creamy green color. Rehoming to someone who might know how to style this! Never used personally so it’s in great quality. Slight color wear on the sides that was there before I purchased. Says size 16 which I’m not sure which sizing group it’s in but I’m a size small/27 waist and it fits me.
