'feminine lingerie for the junior' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

I cannot really see how this works, but
'miss' could be 'girl' (synonyms) and 'girl' is found in the answer.
This explanation may well be incorrect...
