Has anyone every heard of the White Sox wearing a uniform called Pajama Style uniform?

Yep, they were pretty hideous. I remember going to a Ranger game in the season they wore them (or introduced them, if they wore them more than one). The shirt was a golf type shirt with a collar, but I think it had an open (no button) v-neck. The tail of the shirt stuck out and flared with v-groves on both sides of the shirts. The pants just looked like short chinos.

They looked more like NFL referee uniforms than baseball uniforms. Like most of the things Bill Veeck had his hands on (e.g. Disco Demolition night), it was a disaster.
