'foxy females' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'formerly in places' is the wordplay.
'formerly' becomes 'ex' (prefix meaning former or onetime).
'in' means one lot of letters goes inside another.
'places' becomes 'spots' ('spot' can be a synonym of 'place').
'ex' put into 'spots' is 'SEXPOTS'.
