And the pull-over of a USN enlisted uniform which is wither wool or cotton depending on the season. The USN application fits none of the definitions cited.
I don't think the US Navy wears those anymore, so the correct terminology is a moot question.
Was there a name for the dress blue trousers with the thirteen button flap on the front?
The Navy has gone back to them for a couple of reasons not the least of which is the storage issue aboard ship for the "officer" style uniform. On the sub I had a locker that measured one cubic foot and I could lay my dress uniform under my mattress to keep it looking decent.
I used to call the thirteen button bell bottoms a number of names inappropriate for this forum, especially after a few too many beers. I heard the new uniform retains the look but has a zipper behind the flap to the buttons are mere decorations. I always thought the tradition behind that "crackerjack" uniform was important to keep, still have my tailored uniform with the embroidery inside although I'll never have a 28" waist again and they were tight back then, just a keepsake now.
