This is a Ralph Lauren golf vest. I purchased it at a Ralph Lauren store overseas. It's a men's item, but I bought it because I thought it was stylish, even though I'm a woman. I think it would fit like a women's size L. The chest width is approximately 51cm. *Please note that there may be some error as I am not a professional. It's been tried on but otherwise stored at home. Please assess the condition based on the photos and consider purchasing. The sides are stretchy, making it easy to wear. It would be great for golf and other activities in the coming season. Shipping will be via Mercari delivery, and the item will be folded for shipping.
