Isabelle Leather Slimline Crossbody Bag with Adjustable Strap
A Rather Splendid Leather Crossbody for Those Who Prefer Organisation to Chaos
Look, we won't pretend this bag solves existential crises. But it does solve the far more pressing problem of where on earth you've put your phone. The Isabelle is that marvellously slim companion you didn't know you needed, handcrafted in the softest genuine leather and designed for people who actually want their belongings to stay put and stay accessible.
Why Choose Our Leather Crossbody Bag
Proper Handcrafted Quality: Each bag is crafted by artisans using only the finest genuine leather. It's soft, buttery, and genuinely lovely to hold. None of that synthetic nonsense.
Thoughtfully Organised: One large main compartment keeps your essentials together, while slip-in pockets, internal zipped pockets, and a full-depth rear zipper pocket ensure everything has its place. Your phone, cards, coins, and the odd lipstick all live here in harmonious order.
Adjustable to Your Life: The shoulder strap adjusts via a simple knot system, dropping to 60 centimetres at its longest. Whether you prefer it snug or draped, you're in control.
Security That Actually Works: RFID protection keeps your cards safe, and the magnetic front flap closure snaps shut with satisfying precision.
Genuinely Versatile: Whether you're heading to the office, meeting friends for coffee, or embarking on a weekend adventure, this bag looks rather good and keeps pace with your life.

SHIPPING + RETURNS
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.

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.
