Women's Hat Styling

Every Lock & Co. hat purchased is carefully and expertly hand-prepared in our London shop by one of our Hatters, before being whisked out of our famous green front door.

If you would like to speak with one of our Stylists, please email us at or use our contact form and one of our team will contact you.


At Lock & Co., we sell the finest hats and caps. To achieve this, we pay particular attention to specific hat characteristics - style, fit, durability, and materials. We share these characteristics with you for each hat to help you decide on the perfect choice.

Find Your Size and Style

At Lock & Co. we offer a wide selection of styles of hats. What defines a hat style is its form: overall shape, height/shape of the crown, width of the brim, and material type. These define a style e.g., Fedora, Trilby, Panama, Cloche, Tweed cap etc.
Pedal Straw Braid
Lock & Co. hats are made of the finest quality material. These can range from exclusive Escorial wool, Scottish Tweed, and cashmere to Toquilla straw for our Panama hat.
Oversized Brim
Different styles of hats have different shapes to them, including classic, fuller, narrow, and standard fits, or with an oversized or a wide brim or sporting a particular shape - bell, birdcage, etc.
