Organisation for ladies and men into wetsuits, possibly (6,9)
I believe the answer is:
womens institute
'organisation for ladies' is the definition.
I can't judge whether this defines the answer.
'men into wetsuits possibly' is the wordplay.
'possibly' indicates anagramming the letters.
'men'+'into'+'wetsuits'='menintowetsuits'
'menintowetsuits' with letters rearranged gives 'WOMENS INSTITUTE'.
'and' is the link.
Can you help me to learn more?
(Another definition for womens institute that I've seen is " Group of females".)
