I'm a little stuck... Click here to teach me more about this clue!

'herself' is the definition.
I can't judge whether this definition defines the answer.

'unveiling she got is ticket to be full of' is the wordplay.
'to be full of' says the answer is hidden in the clue (inside).
'EGOTISTIC' can be found hidden inside 'unveiling she got is ticket'.

Can you help me to learn more?
