Embellishes, with a big fuss, the right directions (6)
I believe the answer is:
adorns
'embellishes' is the definition.
(adorning is a kind of embellishing)
'with a big fuss the right directions' is the wordplay.
'with' says to put letters next to each other.
'a big fuss' becomes 'ado' (I've seen this in another clue).
'the right' becomes 'r' (common abbreviation).
'directions' becomes 'ns' (N is an example).
'ado' next to 'r' is 'ador'.
'ador'+'ns'='ADORNS'
(Other definitions for adorns that I've seen before include "'Decorates, embellishes (6)'" , "Adds ornamentation" , "Bedecks" , "decks" , "Decorates with ornaments" .)
