Gilbert and Sullivan's craft? (8)

I believe the answer is:

pinafore

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

'craft?' is the definition.
(I have seen 'Musical craft' mean 'pinafore' so perhaps 'craft' could also mean 'pinafore')

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for pinafore that I've seen before include "Musical craft" , "It protects female worker" , "Gilbert & Sullivan operetta 'HMS ........'" , "Protective gear" , "HMS -- (G&S)" .)

I've seen this clue in The Globe and Mail.
