Blokes curse boxers et al (8)
I believe the answer is:
menswear
'boxers et al' is the definition.
I can't judge whether this definition defines the answer.
'blokes curse' is the wordplay.
'blokes' becomes 'men' (bloke can informally mean a man).
'curse' becomes 'swear' (synonyms).
'men'+'swear'='MENSWEAR'
Can you help me to learn more?
(Other definitions for menswear that I've seen before include "Ties, say" , "Suits, trousers etc" , "For example, ties" , "Sort of clothing" , "Suits, shirts, ties etc" .)
