Simple and natural in manner (7)

I believe the answer is:

artless

'simple and natural in manner' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for artless that I've seen before include "Free from cunning" , "Clumsy and uncaring" , "Natural - uncontrived" , "Without pretension" , "as an empty gallery" .)

I've seen this clue in the Irish Times (Simplex).
