Reversed so poorly, then drove initially in wrong gear (11)

'wrong gear' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?

'reversed so poorly then drove initially' is the wordplay.
'poorly' is an anagram indicator (a poor spelling).
'then' is a charade indicator (letters next to each other).
'initially' says to take the initial letters.
The first letter of 'drove' is 'd'.
'reversed'+'so'='reversedso'
'reversedso' with letters rearranged gives 'overdresse'.
'overdresse'+'d'='OVERDRESSED'

'in' is the link.

Can you help me to learn more?
