Booooo!!
It's really mean of the Nu!Trek costumers to use a standard element of costuming that simply cannot be replicated so you have to buy it from the official source if you want to cosplay as a Nu!Trek crewmember. Even if you manage to do the weird shiny seams at the top, the fabric isn't one that's available anywhere, and can't be made.
I feel they did that on purpose to piss off the cosplayers.-
