ST uniforms concept

my own take on some star trek uniforms C=
the USS Volania is the science vessel my trek OCs are on C;
this will be updated when I got designs for things like hazard- and environmental suits, or special away team uniforms , as well uniform for higher ranks.
I gave the regular uniforms diffrent deparment colors so you can have an idea of what they would look like in each color , all the regular uniforms are evailable in each department.
I left the badges blank and the rank that can be seen there is lieutenant commander.
