Close to confiscating girl's flute? (5)
I believe the answer is:
glass
'flute?' is the definition.
(flute is a kind of glass)
'close to confiscating girl's' is the wordplay.
'close to' suggests the final letters (the close/ending of).
'girl's' becomes 'lass' (lass is a kind of girl**).
The last letter of 'confiscating' is 'g'.
'g'+'lass'='GLASS'
(Other definitions for glass that I've seen before include "Tumbler or flute?" , "Transparent substance" , "Tumbler, mirror" , "Transparent solid" , "Something to drink from" .)
