Specially prepared do with material that's incredible (6-4)

I believe the answer is:

tailor-made

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

'do with material that's incredible' is the definition.
I can't judge whether this definition defines the answer.

'specially prepared' is the wordplay.
'specially' becomes 'tailor' (I am not sure about this - if you are sure you should believe this answer much more).
'prepared' becomes 'made' ('make' can be a synonym of 'prepare').
'tailor'+'made'='TAILOR-MADE'

Can you help me to learn more?

(Other definitions for tailor-made that I've seen before include "Designed specially" , "Created for a particular purpose" .)

I've seen this clue in The Independent.
