First, Alley's Saavik had a red tunic instead of the white tunic we see with the later command uniforms.
Next, the strap was in red instead of white.
The inside of the flap is in divisional tan instead of white.
And finally, the left cuff is in red with a strip of white instead of being solid white, and she doesn't wear any pips & squeaks.
My customer is going to be wearing the uniform at a convention next weekend, so hopefully I'll be able to share some pics of the uniform on a person soon! :)
