becoming

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

'lovely' is the definition.
(I've seen this before)

'second church that looks to the west in crosby?' is the wordplay.
I cannot really understand how this works, but
'second' could be 'b' (B can mean second eg B-side) and 'b' is found within the answer.
'in' is present in the answer.
This explanation may well be incorrect...

'that's' is the link.

Can you help me to learn more?

(Other definitions for becoming that I've seen before include "Undergoing a change" , "suitably elegant" , "Developing into" , "Befitting or enhancing" , "Suitable; fitting" .)
