    Your Hat Box is Empty



    Take a tape measure and measure around your head, just above your ears, in either inches or centimetres. All of our hats and caps come sized and you can choose which sizing scale you wish to use. We’ve set the default to European sizing which is centimetres.

    The classic way to style your brim is flipped down at the front, and curled up at the back. However all of our brimmed felt hats can be worn with their brims turned back and front. Hats can also be worn on the back of the head but make sure to go down a size if so.

    Over time the natural fibres in our hats and caps may reduce its size slightly, usually if the piece has been subjected to rain or any dampness. To stretch your hat back to its original size, we recommend using a hat jack - you can find our top tips for using a hat jack on our 'Hat Care' page.

    Do not place on a radiator! You should always allow your hat or cap to dry naturally in a warm place.

    Panamas must always be handled by the brim and not by the crown. Handling a Panama by the crown will cause the material to irreversibly split.

    Unfortunately it is not possible to increase the size of a top hat. However our Master Hatters can alter the shape if there are gaps between the hat and your head by using the Conformateur. For this we suggest booking an appointment to visit us in the shop along with your hat so that we can take a look - use our online enquiry form on the 'Contact Us' page.

    Yes, but only for items purchased in our shop, not online. We have a small selection of mono and multi-tone band and bows that we can attach to your hat. You can supply your own band for the hat if your prefer. For the band and bow on your hat we charge £45.

    Although we will always personally inform you of the waiting time when you visit us, all band & bow changes can take up to three days.


    Yes, all of our couture headpieces are thoughtfully crafted in the workroom of our St. James's Street shop by a team of skilled milliners.

    Depending on the style of the hat chosen, typically a couture headpiece is fitted with a comb and/or a hair elastic. Elastics come in a range of tonal colours to suit the wearer's hair colour.

    Women's couture hats that have been "made to order" and customised for the customer are not eligible to be returned for a refund.

    Please be aware that custom-made women's couture hats cannot be returned for a refund once they have been "made to order" for the buyer.


    Occasionally we may run out of sizes online but be sure to choose to be notified once it comes back into stock. You’ll then receive an email from us with a link to our website to buy the item.

    Whilst Lock & Co. items are stocked in shops around the world, these pieces are unique to our wholesale clients and are not a mirror-image of our extensive range on our website and in our shop.


    Our shop is open from 9.30 am to 5.30 pm, Monday to Saturday.

    Our shop dates back to the 1700s and is full of original and quirky features. If you’re visiting us for the first time we’ll always make sure we tell you about our history but you are also free to browse our newly renovated Heritage Room at the back of the shop. Here we have a curated collection of archival content such as Sir Winston Churchill and Admiral Lord Nelson’s ledgers, the first-ever Bowler hat, celebrity head-shapes and much more.

    We are always happy to let customers take photos of our shop, inside and out.

    However if you are wanting to do a photoshoot or film for a media company, please email jon.holt@massey.co.uk.

    Please note that due to popular demand, we are not able to facilitate every request.
