Short platform for men only (4)
I believe the answer is:
stag
'men only' is the definition.
(I've seen this before)
'short platform' is the wordplay.
'short' means to remove the last letter.
'platform' becomes 'stage' (stage is a kind of platform).
'stage' with its last letter taken off is 'STAG'.
'for' acts as a link.
(Other definitions for stag that I've seen before include "speculator wanting quick profit" , "Hunted animal" , "No women allowed" , "Stockmarket operator gambling on a quick profit" , "Adult male deer, often with antlers" .)
