Seated awkwardly, but dignified (6)
I believe the answer is:
sedate
'dignified' is the definition.
(I've seen this before)
'seated awkwardly' is the wordplay.
'awkwardly' is an anagram indicator.
'seated' anagrammed gives 'SEDATE'.
'but' is the link.
(Other definitions for sedate that I've seen before include "Not very exciting" , "Unhurried; drug" , "Calm, unhurried" , "Collected" , "Unexciting" .)
