Resistance Uniforms

[AgentofChaos]

I've noticed that a lot of the members of the Resistance at the base are wearing jackets and vests with the resistance logo on them and they all seem to be somewhat similar in construction and color. I can't seem to figure out if these are all some sort of old military uniform or if they're custom for the film.
I was wondering if anyone could ID jackets or vests that have this sewing pattern of vertical lines.

I liked the look of these outfits too. Hoping a few more reference photos come to light soon...
