She's presumably come out of her shell (5)

I believe the answer is:

pearl

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

'she's' is the definition.

I can't explain the rest of the clue.

(Other definitions for pearl that I've seen before include "Oyster growth" , "Lustrous structure inside an oyster-shell" , "prized example" , "Drop" , "Girl < , pretty" .)

I've seen this clue in the Evening Standard.
