'neatly groomed' is the definition.
The answer and definition can be both related to bodily activities as well as being past participle verbs.
Perhaps you can see a link between them that I can't see?

'prince adjusted sails after leaving thailand' is the wordplay.
'prince' becomes 'p' (abbreviation).
'adjusted sails' becomes 'trimmed' (I've seen this in another clue).
'after leaving' indicates named letters should be taken away.
'thailand' becomes 'T' (abbreviation on car registration plates).
'trimmed' with 't' taken away is 'rimmed'.
'p'+'rimmed'='PRIMMED'
