Wear the same clothes more when static (10)

I believe the answer is:

changeless

I'm a little stuck... Click here to teach me more about this clue!

'static' is the definition.
(thesaurus)

'wear the same clothes more' is the wordplay.
'wear' becomes 'change' (change is a kind of wear).
'the same clothes more' becomes 'less' (I am not sure about this - if you are sure you should believe this answer much more).
'change'+'less'='CHANGELESS'

'when' is the link.

Can you help me to learn more?
