I forgot to add, this might be creative licence on the artist's part, but I like how Riker's top seems to be a light jacket of sorts with an undershirt in the first panel. I've lamented about the TNG uniforms looking a bit dated because of its colors, but having it be a bit more laid back, with a somewhat loose but standing collar and a relaxed but still fitted cut (definitely less formal and thinner than Picard's jacket) would help balance out the color, I think. Relaxed, but still within regulation. If not that, it would be good for away missions as a field jacket. To compare, Geordi's uniform is much closer to the actual uniform in the same panel.
