It's one way, coming back from the clothes shop (8)
I believe the answer is:
singlets
'from the clothes shop' is the definition.
I can't judge whether this definition defines the answer.
'it's one way coming back' is the wordplay.
'it's one' becomes 'single' (synonyms).
'way' becomes 'st' (abbreviation for street).
'coming back' says the letters should be written in reverse.
'st' reversed gives 'ts'.
'single'+'ts'='SINGLETS'
Can you help me to learn more?
(Another definition for singlets that I've seen is " Garments".)
