The fresh air around Maidenhead suits her (4)
I believe the answer is:
irma
'her' is the definition.
(I've seen this before)
'the fresh air around maidenhead' is the wordplay.
'the fresh' is an anagram indicator (a fresh re-ordering of the letters).
'around' indicates putting letters inside.
'maidenhead' becomes 'm' (head letter of 'maiden').
'air' is an anagram of 'ira'.
'ira' placed around 'm' is 'IRMA'.
'suits' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for irma that I've seen before include "- La Douce, nineteen sixty three Billy Wilder film" , "The girl for Irish music award" , "Girl's name ("La Douce")" , "1963 film with Lemmon and Maclaine" , "- la Douce (1963 film)" .)
