I don't understand why it took so long for them to make this uniform, it doesn't look that complicated to me, a pretty simple outfit. Regardless, for it being from the 29th century you'd think it would be more advanced. That's one thing I never liked about what we saw from the 29th century, their uniforms should be active systems that like harden on impact, providing protection, and have like personal shields built in. We are talking about a time period 400 years from STO's time period. A lot can happen in 400 years, and should have happened and things progressed a bit more when it comes to uniforms and their abilities on officers.
