A prim lady somehow got into shape (9)

I believe the answer is:

pyramidal

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

'into shape' is the definition.
I can't tell whether this definition defines the answer.

'a prim lady somehow' is the wordplay.
'somehow' indicates an anagram.
'a'+'prim'+'lady'='aprimlady'
'aprimlady' anagrammed gives 'PYRAMIDAL'.

'got' is the link.

Can you help me to learn more?

(Another definition for pyramidal that I've seen is " The kind of orchid".)

I've seen this clue in The Daily Express.
