Why were there two versions of the collared uniforms in Star Trek: TNG Season 3?

Star Trek: The Next Generation season three introduced the collared uniforms. But while re-watching the series, it looks to me like there were two versions of the collared uniforms. When season 3 started, the uniforms had seams in the chest (to make them more form-fitting?). These two IMDB images from "Evolution" show them well:

But by episode 6 ("Booby Trap") the seams on the chest seem to have disappeared from Picard’s uniform…

But were still present on other cast members:

But by episode 10 (at least) the seams had also disappeared from other cast members:

The story of undersized, tight uniforms to reduce wrinkles and Patrick Stewart’s back pain contributing to a redesign is pretty well documented. But I’ve never read anything about another, partial redesign part-way through season three.

Question: Is there a story behind this additional uniform change in season three? For example why were the seams used to begin with? And what lead a second redesign to remove them?
