The Panama Envelope bag is a well-recognised silhouette within the fashion atmosphere, catapulted to fame thanks to its heritage as an offering from esteemed Bond Street staple Smythson in central London. Here, the profile is transformed into an on-the-go phone case, with a handy cross-body strap for if you need to go hands-free. Smythson is one of only seven companies to have been granted a Royal Warrant from His Majesty The King and Her Majesty The Queen, recognising its ongoing role as a supplier of goods to the Royal Family.
