There were many who said the onesie would never catch on, that people would never like to restrained in what was essentially a furry straight straitjacket but how wrong they all were.
Onesies have taken over, everyone has one and now they have evolved into a new invention, the twinsie, the onesie for two.

It has three legs, four arms and two heads and costs about 50 euro and can be ordered here.
Interesting.
