Not familiar with Army unifoms, but still posting?
Our blue uniforms are traditional, and have never had a linear break. They’re modified over the last century, but basically the same.
Again, it was the USMC that copied the Army with the blue uniform. Not that hard to look it up.

And, here's a picture of an airborne NCO wearing the Class B uniform:
In my opinion, the Army could not have made it more hideous if they had tried. Earlier, they had considered a grey shirt which looked much more military and did not permit jump boots. This is Gawd Awful, it looks like a cross between a security guard in an art museum and the drill team for the Gay Caballeros marching band. The only thing missing is the red silk sash around the waist.
All of this comes from too many compromises and too many attempts to please everyone. No danger that anyone will accuse the Army of copying the Marines, we could only wish that someone would consider that option.
Agreed the Army once wore blue, but the Army is similar to a woman who can’t make up her mind about what she wants to wear.
