Handmade for You by a Team of Master Craftsmen

Posted on: 06/03/2020

Since 2008, we have made it our mission to share warmth, fun and happiness with people all over the world – and what a journey it has been!  Over the past 8 years, we have handmade over 61,000 onesies right here in the UK, delivering to over 200 different countries Worldwide.

As proud members of Made in Britain, here at The All-in-One Company, British Manufacture is extremely important to us. Full of integrity, our creative process embraces the diversity of modern Britain today with all it’s traditions and contradictions. All of our Onesies are ethically handmade right here in the beautiful county of Northumberland.

We know that everyone is unique, so rather than offering you a collection of off-the-shelf products, we offer you the chance to Create your very own Onesieon the 3D Onesie Builder.

Create the Onesie you wish Existed


Our beautiful fabrics are hand picked by our team for quality, softness and stretch. We have put together a collection with your comfort in mind. See our fabric guide for the full details and care instructions to find the right fabric type for you. With our fabric ranges being available all year, you can be snug or cool whatever the season.

We even offer a free Fabric Swatch Service, so if there are any fabrics you'd like to see before ordering, you can just let us know and we'll put together your Fabric Sample pack with the specific fabrics you requested.


Each Onesie is individually cut, sewn and embroidered with pride by our team of Master Craftsmen using traditional skills that have been passed down through generations.

Since each Onesie is made to order, we offer our complimentary Made to Measure Service. We are all unique and our sizing reflects our differences. Just let us know your specific measurements in the Order Instructions box at the checkout.

Unlike most bespoke items, your Create-your-Own Onesies are made and dispatched with 7 - 14 days. 

We even cater for special dates, so if you need your Onesie before a certain date, whether you're celebrating a birthday, anniversary or any other special occasion, you can let us know in the Order Instructions Box at the checkout and our team will do their best to get your Onesie out to you in time. 

If you need your Onesie in a hurry, our "Express Manufacture" Service option is available within the checkout. 

Your order will be handmade and dispatched within 3 working days.

*Additional £20 per item. 


Just like our products, our Customer Service is second to none. We'll happily go above and beyond to make sure you receive the best service possible. Our team will answer any questions or queries you have, big or small, over the phone, email, and even Facebook message.


As part of our commitment to the environment we offer the TLC service.

For £25 plus delivery you can return your Onesie for a pampering session, it will receive a new zip, new cuffs and new soles of the feet. 

So much better to be able to repair your loyal trusted Onesie companion rather than replace it completely, when it just needs a little TLC...


When we're not making Onesies, you can find us enjoying a tea break in the snack room.

We all spend our break times together, and our Play Committee often leaves treats for us to enjoy.

We see each other as family here at The All-in-One Company, supporting each other through work and life. Evenings and weekends are precious hours spent at home. All staff members can have time off to see their children at sports days and nativity plays so those special moments are not missed.


Our Play Committee, formed by a few members of our team, are always there to organise lots of fun things for us at work, from throwing company birthday parties, to Halloween parties, baking cakes and treats, secret santas, treating the team to chocolates at break time during the busiest months.
We also treat the team to a cake, card, balloons and present on their birthday!

The Play Committee also organise fundraising events such as the Macmillan Coffee Morning, Race for Life, Red Nose Day (Comic Relief) and Children in Need. They also come up with little surprises to make coming to work a fun and an exciting thing to do.
