Legal statement gets Edward ruffled (7)
I believe the answer is:
pleated
'ruffled' is the definition.
('pleat' can be a synonym of 'ruffle')
'legal statement gets edward' is the wordplay.
'legal statement' becomes 'plea' (plea is a kind of statement. I am not sure about the 'legal' bit.).
'gets' is a charade indicator (letters next to each other).
'edward' becomes 'ted'.
'plea'+'ted'='PLEATED'
Can you help me to learn more?
(Other definitions for pleated that I've seen before include "Given creases" , "Gathered" , "Folded and sewn" , "(Garment) with folds" , "Folded and stitched" .)
