Shiny fabric? Implausible (4)

I believe the answer is:

lame

This clue is a double definition.

'shiny fabric?' is the first definition.
'lame' can be an answer for 'fabric?' (lame is a kind of fabric). I also know that 'shiny' relates to this answer.

'implausible' is the second definition.

(Other definitions for lame that I've seen before include "Imperfect - material" , "Limp - fabric" , "Of excuse, weak and unconvincing" , "game" , "Disabled in the feet or legs" .)

I've seen this clue in The Everyman puzzle in The Observer and The Sun.
