One might be seen in this car next to bypass (9)
I believe the answer is:
miniskirt
'one might be' is the definition.
The definition suggests a singular noun which matches the answer.
'this car next to bypass' is the wordplay.
'this car' becomes 'mini' (Mini Cooper).
'next to' says to put letters next to each other.
'bypass' becomes 'skirt' (I've seen this in another clue).
'mini'+'skirt'='MINISKIRT'
'seen in' acts as a link.
Can you help me to learn more?
(Other definitions for miniskirt that I've seen before include "This should not be looked up in Chambers!" , "anything less wouldn't be proper" , "Very short garment" , "Popular attire in the 1960s" , "Very short item of female attire" .)
