The test is your only chance to see it before it is bought.
Film renders colour and fabric differently from any monitor, and you cannot check a garment on the floor by looking at a screen. By the time the negative comes back, the costume is made.
So the camera test stops being a camera department errand and becomes the most important day in your calendar.
What to put in front of the lens
Four things worth testing.
The actual fabrics, on the actual people
Not swatches on a board. Skin and cloth together, under the sources the film will use. A colour that sings on a monitor can go flat on negative, and a fabric that read as rich can read as muddy.
Anything black, anything white
Negative holds a lot in the shadows and a lot in the highlights, but deep blacks and bright whites are where a costume decision becomes a lighting problem. Test the extremes and you will not be surprised.
Sheen and synthetics
Anything that catches a highlight — satin, leather, high-vis, anything modern and shiny — behaves differently through a film chain than through a digital one. Look at it moving, not still.
Doubles and continuity pieces
Test the double as well as the hero. Dye lots vary, and on negative the difference can show in a way it never would on a monitor.
On the day
Continuity is carried by notes, not playback.
There is no going back over the take on a monitor to check a collar. Photograph and note as you always would, but assume the still is the record, and be more conservative about changes mid-scene than you would be on a digital shoot.
