'typical of gown' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'fastener opening but not right' is the wordplay.
'fastener' becomes 'stud' (I've seen this before).
'opening' becomes 'entry' (I've seen this before).
'but not' suggests deleting specific letters.
'right' becomes 'r' (common abbreviation).
'entry' with 'r' taken out is 'enty'.
'stud'+'enty'='STUDENTY'

'with' is the link.
