Seemly (6)

I think it could be either:

proper

decent

'seemly' is the definition.
(synonyms)

This is all the clue.

(Other definitions for decent that I've seen before include "Appropriate, fitting" , "Honourable or modest" , "Proper; passable" , "Fitting; satisfactory" , "Moral; fitting" .)

I've seen this clue in The Telegraph, the Sydney Morning Herald, the Evening Standard, The Mirror and The Guardian.
