Our Values


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 60,000 onesies right here in the UK, delivering to over 200 different countries Worldwide.



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-Own Onesie on our Personalised Online All-in-One Onesie builder, which is compatible on desktops, tablets and mobile phones and allows you to create your onesie to your very own specifications.

We feel we have perfected the art of creativity and invite you to see for yourself. Simplicity and fun..all at your finger tips..

Check out our Personalised Onesie Builder and see what you can create!


We maintain a presidential and unquestionable standard throughout the whole of the company, from our team, training, equipment, materials and finished product.

Each Onesie is individually cut, sewn and embroidered with pride by our team of expert cutters and machinists using traditional skills that have been passed down through generations.
As well as being members of The Guild of Master Craftsmen, we've also been awarded our eKomi Gold Seal of approval for scoring 4.9 out of 5 Stars on our Customer Review page.

We pride ourselves on making high quality Products that are made to last, so they will be with you throughout life’s biggest milestones.


All in One Company - June 2013

As each Onesie is individually hand-cut and sewn, we offer a Made-to-Measure Service, so if you want to let us know about any specific measurements or any special requirements you can do so in the Order Instructions box at the checkout.

Since you have the freedom to Create-your-Own Onesie, you can express your personality in any which way you choose.
As well as being able to mix and match various fabrics to Create-your-Own colour combinations, hoods, feet, pockets, ears and tails can be added to your Onesie. You can take personalisation one step further by adding embroidery, whether it be a name, message or image – it’s totally up to you!



Here at The All-In-One Company, we'll always be there for you.
Even before you order, you can get in touch to ask us any questions you may have, whether it's questions about fabrics, sizes, or even add on's.
We'll be more than happy to answer any queries you have.
We'll even send you out a Fabric Swatch Pack so you can see and feel the differences between each of our Fabric Types before ordering.

We've also just launched our Sensory Onesie.
Hand in hand with The National Autistic Society, we worked alongside children affected by Autism to create a Onesie suitable for those with Sensory issues.

We always make sure our Fabrics are high quality, so we carry out a range of tests from cutting and sewing samples, to wash tests, making sure there’s no colour run or shrinkage.
