So, I know this isn't really the thread for this but what is poorly executed of this version? Bearing in mind that I have no service experience but have always appreciated the uniforms and their history in the US Armed Forces.
WAY OT:
For one thing a lot of the tailoring looks bad. Coats like that with a fitted waist and a belt don't look good off the rack on a lot of people. This will probably improve over time though as the system adjusts to the new requirements. They went with dark bronze rather than gold buttons, which is not historical and contrasts poorly with the gold color of the collar and cap insignia. The breast pocket flaps are a weird, too-tall shape. They got rid of the edge piping from the garrison cap, which was a nice bit of accent. The enlisted chevrons are not the historical color scheme with dark blue background. But the worst of all is the visor cap. It looks like a cheap Halloween store knock-off of a USAAF crusher cap. I mean, this thing looks like it's a foot tall in the front, it's cartoonish.

I would note that General Milley has had his own cap made with much more traditional styling. He also wears old-school sliver embroidered general's stars.
I do like the return of the full-color shoulder patches, though.
