Tea with Doctor Charles in smooth light linen fabric (8)

I believe the answer is:

chambray

'smooth light linen fabric' is the definition.
(chambray is a type of fabric)

'tea with doctor charles' is the wordplay.
'tea' becomes 'cha' (cha is a type of tea).
'with' says to put letters next to each other.
'doctor' becomes 'MB' (Bachelor of Medicine, Medicinae Baccalaureus).
'charles' becomes 'Ray' (Ray Charles).
'cha'+'mb'+'ray'='CHAMBRAY'

'in' acts as a link.

(Another definition for chambray that I've seen is " Mary Bach makes a lightweight woven fabric".)

I've seen this clue in the Sydney Morning Herald.
