"Fantastic service all around. Excellent customer service, very easy ordering and design process, and very professional and high quality craftsmanship.
I collect custom-made onesies and have done for years, and this is one of the best ones that anyone has ever made for me. I ordered a onesie based on a design drawn by myself and their staff were incredibly helpful in making sure that they understood the design as much as possible when I contacted them, asking me to clarify anything that was needed and being very polite and helpful through the whole process. It was finished surprisingly quickly in about a week and arrived the next day. The end result was pretty much perfect, exactly what I asked for down to every detail, and incredibly professionally made. Absolutely worth the price and I will definitely be ordering from them again soon."

"super happy with my onesie! it's probably the best item of clothing I've ever owned and I have a lot of trouble removing it as I like it so much.
super soft and warm, I was also very impressed with how quickly I received it considering I'm on the other side of the world in new Zealand."

"As always (this was the 5th onesie i ordered) they delivered absolute perfection. These people cater to all my quirks and needs (an extra inch here, some extra length in the arms, attached mittens without turnbacks) and i love them for it. Ordered a onesie in "plush jersey sweatshirt" this time and it's an absolute dream to wear! super soft, super stretchy, not too warm... really... it's about time it becomes normal to wear a onesie to work or anywhere because i really don't want to wear anything but these people's creations!"

"Fantastic, amazing and super comfortable.
Just received my second All in One co onesie and i love it.
The premium cuddle fleece is verry soft and warm, so nice you don't want to take the onesie of again.
Keep on going the great work.
Thanks from The Netherlands"

"Ordered one of these for my girlfriend as a birthday present and she absolutely loves it.
The build and material quality (went with the premium cuddle fleece) is excellent and it just looks great.
Because it was bespoke I had to use the website to design it and it was so easy to use. I was able to design it exactly the way i wanted it and it turned out exactly as I hoped.
One very happy girlfriend. Excellent customer service"

"Dear Onesie HQ
So happy with my latest order and the process I went through to get it right. from the initial enquiry to the amendments to the delivery... The All In One Company once again delivered on every aspect of the buying cycle.
This onesie was possibly my most outlandish design and Kate & the team perfected it. It arrived just a few days ago and I LOVE it... Also must mention how fast it got here... Just 4 days from despatch to delivery.. All the way from Ashington to Melbourne..
SO SO HAPPY!! I wish I could give you a million stars for the rating :)"
