The All-in-One Company®


it all started with sleepless nights. Kate needed to keep her daughter Lilly warm at night. Lilly had grown out of baby grows and there weren't fleece sleepsuits for older children back in the day. So, the concept of create-your-own onesies in any size, fabric, with any add-ons of your choice was born in 2008. The All-in-One Company was launched in the October and has never looked back. We now have accessories to add to our range of products that are handmade to order especially for you.
Production Methods

Our highly skilled master cutters hand cut your completely customised onesie in your chosen design and fabrics, using traditional cutting skills passed down through generations. As members of The Guild of master craftsmen, our master machinists will sew your premium Onesie with love and care.

"Seeing things being made is totally inspirational. Having something made especially for you is exceptional. I'm very proud to manufacture in Northumberland and to lead such a fabulous team of makers."
– Kate Dawson, Managing Director.

All of The All-in-One Company onesies are handmade in their factory in Northumberland by their highly skilled team.


The All-in-One Co source the majority of their components from the UK - trims, zips, packaging (bio-degradable), plain fleece. They do use UK suppliers to source the remainder of their plain fleece, patterned and cuddle - although this can be imported from overseas, such as Italy.
