I have been find most AB clothes are made in UK not USA there very few shop do this type product for AB USA.Also alot USA stores have found they charge more than UK ones do
so I may order out UK if can't find any good places in USA
In the USA and Canada there are many fine firms selling cloth diapers and garments for AB. Of course most of these garments and diapers are also worn by incontinent people and those with physical limitations.
My adult flat gauze diapers come from Adult Cloth Diaper Company. I use ordinary Gerber Birdseye baby prefolds as the soaker. Those are sold in some ordinary stores at reasonable prices. I have never looked to find them but probably they are sold online. My soft vinyl pull-on pants come from the Kins department of Babykins which is in Canada. There are a lot of USA waterproof pants suppliers. I have bought from Babykins for 20 years without problem and find their prices fair.
My youngest sister Missy designed the Onesies and other AB clothing we wear. When she is very busy our Mom does the sewing. Friends of mine buy AB clothing from ACD and Kins, as well as many other popular dealers. Onesies and footed sleepers need to fit correctly so often they need to be custom made.
