100% cotton. Brushed cotton fabric. Full button fastening. Chest Pocket. Regular fit. If youve not been living under a rock and are vaguely familiar with how a classic Oxford Shirt should behave, something like this Portuguese Flannel Brushed Oxford Shirt might spring to the frontal cortex. This one has been made from some super-stout flannel fabric thats been brushed to proverbial perfection and bestowed with one singular pocket for any receipts, wrappers and bus tickets you wanted to keep hold of (but should definitely throw away).
