Being a little economical, I costed plain white fabrics (7)

I believe the answer is:

calicos

'plain white fabrics' is the definition.

'being a little economical i costed' is the wordplay.
'being a little' indicates a hidden word.
'CALICOS' is hidden in the letters of 'economical i costed'.

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