There were only four new outfits sold in 1984.
One of them was outfit #20, the sailor romper, which is often associated with the 1983 series. I believe that it was originally intended to be a part of that series and, for some reason, not produced until the next year.
The other three outfits are knit and were produced ONLY by the EX factory. They do not have codes like the other 1983 outfits. There are no letters or numbers.
Most of them came separately packaged. In later years, occasionally they can be found on boxed kids as they were getting rid of inventory.
I am unsure how long these outfits were produced but, given that they are rarely seen, I don’t believe it was very long.
