Villager Sport Woman Vintage Sleeveless Buttoned Blue Brown Floral Top Size 2

Villager Sport Woman (A Liz Claiborne Co.) Vintage Sleeveless Buttoned Blue & Brown Floral Top Size 2 (2X). States a size 2 but is definitely a plus size. Not sure what that would convert to. Please see measurements included: length 27". Pit to pit 24" max. I was unable to get sizing chart for this brand as it is vintage. SS#6
