Ralph Lauren Oxford Zip Shirt in Black. Garment dyed to intensify the deep shades in its base, this zipped shirt from American icon Ralph Lauren is constructed in the brand\'s classic fit. The silhouette secures with a silver-toned zipper, whilst at the neckline, Mother of Pearl buttons are borrowed from the label\'s traditional shirting styles in order to create a throat tab. To finish, the signature pony embroidery is placed upon the chest alongside a patch pocket.
