The style that started it all. We first designed the Signature Shirt with the intention of sprucing up the casual shirt. We do that through detailing (refined but not rigid), fit (drapey but not too drapey), and fabric (always natural, always low impact, always the best quality).  

For AW25, we've updated the design and ventured into the world of Cotton Cashmere. Is there anything softer than a midseason marriage between Brushed Cotton and Cashmere? We're yet to see it. 

Our model is 6'1 with a 39 inch chest and wears a medium.

• 95% BCI Cotton & 5% Cashmere
• Straight Fit, Shoulder Pleats
• Rounded Two-Button Cuffs
• Made in Northern Portugal
• Free from Single Use Plastics
• Machine Washable

Returns and Exchanges Policy

We hope you love your purchase, however, if you change your mind unwanted items can be exchanged or returned within 14 days of your order’s delivery date.

Our 14-day return policy means you have 14 days after receiving your item to notify us if you wish to return it. Once you notify us, you then have a further 14 days to return the item.

All returned items must be in their original, unworn, unwashed condition, including all tags. We do not offer free returns, instead the customer must cover the cost of postage. For UK customers, a postage label will be generated within our Returns Portal (more information below). For international customers, please use our Returns Portal to create the return and then please use your own choice of service for return shipping.

Refunds will be processed within 30 days of receiving the goods. However, please note, for exchanges the new item dispatched from our distribution centre will be sent free of charge.

As a first port of call, we’ll do our best to address any concerns you might have about your item(s). Please send an email to of@originalfibres.com with any questions you have – you will receive a reply from one of our small team, addressing your specific queries. Never automated advice. If we don’t have what you’re looking for online, there’s a good chance we have it at our shop, so we will do our best to make the desired exchange happen.
