Tips for hot-weather clothing perhaps try one’s patience (4,4)
I believe the answer is:
wear thin
'perhaps try one's patience' is the definition.
I can't tell whether this definition defines the answer.
'tips for hot-weather clothing' is the wordplay.
I cannot quite understand how this works, but
'hot' could be 'in' (both can mean fashionable) and 'in' is found in the answer.
'clothing' could be 'wear' (synonyms) and 'wear' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for wear thin that I've seen before include "Become threadbare" , "Cease to convince" , "Get less convincing" , "Become less convincing through overuse" , "start to be ineffective" .)
