North African tabard, say, shortened by Welsh girl (8)

I believe the answer is:

tunisian

'north african' is the definition.
(I've seen this before)

'tabard say shortened by welsh girl' is the wordplay.
'tabard say' becomes 'tunic' (tabard is a kind of tunic).
'shortened' means to remove the last letter.
'by' says to put letters next to each other.
'welsh girl' becomes 'Sian' (common Welsh name).
'tunic' with its final letter taken off is 'tuni'.
'tuni'+'sian'='TUNISIAN'

(Another definition for tunisian that I've seen is " North African native".)

I've seen this clue in The Times.
