Almost perfect clothes for hobby (7)
I believe the answer is:
pursuit
'hobby' is the definition.
(I've seen this before)
'almost perfect clothes for' is the wordplay.
'almost' means to remove the last letter (almost the whole word is kept).
'perfect' becomes 'pure' (synonyms).
'clothes for' becomes 'suit' (I can't explain this - if you can you should give a lot more credence to this answer).
'pure' with its last letter removed is 'pur'.
'pur'+'suit'='PURSUIT'
Can you help me to learn more?
(Other definitions for pursuit that I've seen before include "courting?" , "See 1" , "Search" , "Interest" , "The chase or the occupation" .)
