As worn by mother a lot? (3)
I believe the answer is:
mac
'as worn by mother a lot?' is the definition.
I can't judge whether this defines the answer.
'by mother a lot?' is the wordplay.
'by' is a charade indicator (letters next to each other).
'mother' becomes 'ma' (ma can mean mother).
'a lot?' becomes 'c' ().
'ma'+'c' is 'MAC'.
Can you help me to learn more?
(Other definitions for mac that I've seen before include "one used in shower?" , "Raincoat (colloq.)" , "Waterproof coat (colloq.)" , "It may help you keep dry" , "Overcoat" .)
