What may be used to select the right gear? (5,5)
I believe the answer is:
dress sense
'what may be used to select the right' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'gear?' is the wordplay.
I cannot quite see how this works, but
'gear?' could be 'dress' (both can mean clothing) and 'dress' is found within the answer.
The remaining letters 'sense' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dress sense that I've seen before include "Good instinct for selecting garments" , "What fashion icons have" , "Instinct for clothes" , "Good taste in clothes" , "style" .)
