Rather Rather Rather Good Dog Harness That Actually Fits
Look, we'll be honest. We've somehow managed to collaborate on a harness that's rather good. It's ocean blue, properly tailored, and channels the sort of understated craftsmanship you'd find on Savile Row, only considerably smaller and designed for pups instead of chaps in expensive suits.
Why Choose Our Mayfair Harness
Beautifully crafted with meticulous attention to detail. This is a limited-edition piece that pairs smart simplicity with genuine quality, because your dog deserves to look fabulous on walks without you feeling like you've spent a fortune on, well, dog furniture.
Splendid tailoring. Sharp lines, clean finishes, undeniably rather handsome. It's the sort of harness that makes you look like you've got your life together, even if you absolutely haven't.
Works with all sizes. Available from XXXS to XL, which means we've (hopefully) got your dog covered, whether they're a teacup or a small bear.
Product Details
Material: Premium crafted construction designed to last through countless walks, muddy puddles, and the occasional overenthusiastic squirrel chase.
Sizing: XXXS to XL available, so there's a rather good chance we've got your pup's measurements sorted.
Matching set available: Pair this with the companion harness in the Mayfair Set for just 44.98 pounds and save 5 pounds. Marvellous value, really.
Limited edition collaboration. This is a one-off pairing between two brands that actually care about doing things properly. When it's gone, it's gone.
Treat your dog to something rather splendid. Order now and give your pup the most delightfully stylish walks on the block.

THE RATHER IMPORTANT BITS
This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.
SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.
Some are brilliant at international shipping, others prefer to keep things closer to home.
At checkout, you'll see exactly where this particular brand can send your goodies.
We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!
RETURNS
You have 14 days to return items.
Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!
🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.
Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!

We Have Lots More Like This.........
Hello, we are Sostter....
Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?
We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect.
Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience. Every object tells a story, and every purchase supports an independent brand doing things differently.
This is just the beginning. But enough about us — step inside, explore our world, and see what catches your imagination.
Giving Back
We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.
