Easily spotted by its bright orange door, you won't miss Petershams Millinery Supplies at The Artworks, Elephant & Castle's equivalent to Boxpark in Shoreditch.
Founded by Californian Michelle Osborne, this is a place you'd come to get everything you could need to make a hat, fascinator or elaborate headband.
Rolls of fabric line the walls, crowded with feathers, trims, bases, pins, combs, veiling and all kinds of decoration. There's also a box of vintage hats – for viewing purposes only – in case you're after a little inspiration.
