Right to probe neckwear teacher wore experimentally (5,2)
I believe the answer is:
tried on
'wore experimentally' is the definition.
'tried on' can be an answer for 'wore' (trying on is a kind of wearing). I'm not sure about the 'experimentally' bit.
'right to probe neckwear teacher' is the wordplay.
'right' becomes 'r' (common abbreviation).
'to probe' means one lot of letters goes inside another (probe can mean to poke into).
'neckwear' becomes 'tie' (type of neckwear).
'teacher' becomes 'don' (don is a kind of teacher).
'r' inserted within 'tie' is 'trie'.
'trie'+'don'='TRIED ON'
Can you help me to learn more?
(Other definitions for tried on that I've seen before include "tested for suitability" , "Checked shirt perhaps" , "Tested the fit of (a garment)" , "Donned a garment to see if it suited" .)
