ostrich feathers

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

'boas' is the definition.
I know nothing about this answer so I can't tell whether this works.

'amongst the almost rich feat hers are' is the wordplay.
'amongst' indicates the answer is hidden within the clue.
'OSTRICH FEATHERS' is hidden within 'almost rich feat hers are'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
