'not even stylishly' is the definition.
I can't judge whether this definition defines the answer.

'not even stylishly' is the wordplay.
'not even' becomes 'odd' ('odd' is the opposite to 'even').
'stylishly' becomes 'ly' (I can't justify this - if you can you should give a lot more credence to this answer).
'odd'+'ly'='ODDLY'

Can you help me to learn more?
