Indulge in memories: half receding, about short skirts (9)

I believe the answer is:

reminisce

I'm a little stuck... Click here to teach me more about this clue!

'indulge in memories' is the definition.
I can't tell whether this defines the answer.

'half receding about short skirts' is the wordplay.
'half' means to take half the letters.
'about' indicates putting letters inside.
'short skirts' becomes 'minis' (mini skirts).
'receding' cut in half is 'rece'.
'rece' placed around 'minis' is 'REMINISCE'.

Can you help me to learn more?

(Other definitions for reminisce that I've seen before include "Talk about old times - I'm sincere (anag)" , "Say what one remembers" , "Remember past" , "Recollect past events" , "nostalgic" .)

I've seen this clue in the Sydney Morning Herald.
