I believe the answer is:

selfportrait

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

'something that's so like her' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'a pert florist arranged' is the wordplay.
'arranged' indicates an anagram (letters rearranged).
'a'+'pert'+'florist'='apertflorist'
'apertflorist' is an anagram of 'SELFPORTRAIT'.

Can you help me to learn more?

I've seen this clue in The Irish Times.
