Why would they make these so faithful to TOS era and abandon TOS design cues in the uniforms and ship (Shenzou) and just about everything else. If we didn't already see Lorca in the chair in uniform, I'd think they might have been misleading us regarding the final uniforms and not shown DSC's yet. Too much to hope for.
I love the design but it doesn't fit the with more Kelvin look we're seeing elsewhere. Not as bad as the cotillion-gowned Klingon debutantes at least.
The shenzou is faithful the ENT, not TOS which is 50 years old and very dated. The cage uniforms were also fugly as all get out, they left hints of those uniforms, but really went with more of what Trek became later. TOS is always the odd duck out, its uniforms and ships look little like anything that came after.
