Our Westcott Polo is a case in point - beautifully crafted from 100% organic cotton jersey and featuring a relaxed resort collar, this ecru style is a great addition to your summer tailored looks, but can equally be worn as part of a laid-back vacation wardrobe.","images":["https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01ECRFRONT_6a03ce7b-3106-464c-a8ed-7a3a7b93c69b.jpg?v=1777882027","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01ECRDETAIL1_f730fa8e-dda9-41e6-9152-e21f7596fc6e.jpg?v=1777882028","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01ECRDETAIL2_0ad1c2a2-70fe-4bf0-89d4-f331cd734b9d.jpg?v=1777882028","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01ECRDETAIL3_f7db39e6-607a-4363-8db0-900a5b3e889a.jpg?v=1777882028"],"price":170,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:28.915Z"},"share_url":"https://firestarter.network/l/lst_TocQkcwF","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
