Fixed tattered catsuit and ditched uniform (6)
I believe the answer is:
static
'fixed' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for static that I've seen before include "Not active, immobile" , "Motionless like some kind of electricity" , "Stationary" , "disturbing thing" , "problem with radio reception" .)
