Parodies efforts to pinch a waistcoat for the Americans (10)

I believe the answer is:

travesties

'parodies' is the definition.
(travestying is a kind of parodying)

'efforts to pinch a waistcoat for the americans' is the wordplay.
'efforts' becomes 'tries' ('try' can be a synonym of 'effort'**).
'to pinch' indicates putting letters inside.
'waistcoat for the americans' becomes 'vest'.
'a'+'vest'='avest'
'tries' going around 'avest' is 'TRAVESTIES'.

(Another definition for travesties that I've seen is " They're ridiculously unconvincing".)

I've seen this clue in The Telegraph.
