Sizing

Since first launching in 2008 we have celebrated uniqueness, that's why we now offer more sizes than ever before.

Our standard sizes now range from 0-3 months to 5 XL.
As members of The Guild of Master Craftsmen, all of our Onesies are handmade to order by our team of expert cutters and machinists. Tailored to you we offer a Made to Measure Service so you can let us know your specific measurements.
Whether you need added sleeve length, a shorter leg length, or extra width for broad shoulders - nothing is too much trouble.
If there are any special requirements, or measurements you would like us to know about, our Development Team will be more than happy to help create the perfect Onesie, tailored to fit you.

You can pop your requirements in the Order Instructions Box at the checkout, or if you'd like to speak to us before ordering, you can do so by Phone: 01670 522478, Email: info@the-all-in-one-company, or our online chat found in the bottom right hand side of our website - we're always here to help.

The Sensory Onesie

Picture22

With over 90% of people with Autism suffering from Sensory issues, we’ve linked up with The National Autistic Society to create clothing that allows everyone to feel Snuggletastic®.

The Sensory Onesie is sewn in a way that seams feel seamless, no labels are sewn into the garment, and there is nothing that causes irritation.

You’re able to choose which fabrics you’d like your Onesie to be made from. We offer a complimentary Fabric Swatch Pack so you can see and feel the difference between each fabric type prior to ordering.

All of our Onesies now come with a Zip Cover, so the back of the zip is covered with fabric, making it soft against the skin.

*Onesies can also be double stitched to prevent ripping or tearing*

We’re also donating 5% of each Sensory Onesie Sale to The National Autistic Society.

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 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.

Our ever-growing Fabric Range is full of Snuggletastic fabrics from Cotton Jersey, Luxurious Bamboo Towelling, Supersoft Cuddle Fleece, Organic Cotton and Plush Sweatshirt – to name but a few! All of our fabrics come in a range of different colours and patterns, so you’re sure to find a fabric, or two, to suit you.
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.

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!
