Vintage Lady Pickering Country Club V Neck Acrylic Sweater Blue women’s size M

Adorable light blue preppy little sweater. I can’t for the life of me figure out what country club this might be from. Any ideas? In good used conditions. Some pilling consistent with age and use but no holes or stains or other apparent flaws. Approximate Flat Measurements Pit to Pit: 19” Length: 21.5” Waistband: 12.5” unstretched Sleeve length: 27” from collar
