Suggest leaving end of webbing out of panel strengthening garment (6)
I believe the answer is:
gusset
'panel strengthening garment' is the definition.
(a gusset strengthens a garment)
'suggest leaving end' is the wordplay.
'suggest' becomes 'guss' (I can't explain this - if you can you should believe this answer much more).
'leaving' becomes 'elopement'.
'end' means to remove the middle letters (I've seen 'ends' mean this).
'elopement' with its centre removed is 'et'.
'guss'+'et'='GUSSET'
'of webbing out of' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
(Other definitions for gusset that I've seen before include "Garment enlarger" , "Strengthening material insert" , "Angular insertion in a garment" , "Piece of inserted material" , "Strengthening material in a garment" .)
