'bit of gear' is the definition.
The definition suggests a singular noun which matches the answer.

'set trend off with small' is the wordplay.
'off with' indicates an anagram.
'small' becomes 's' (abbreviation - e.g. clothes size).
'set'+'trend'='settrend'
'settrend' with its letters anagrammed with 's' can make 'TENT DRESS'.
