Girl out of breath? (6)

I believe the answer is:

bertha

'girl' is the definition.

'out of breath?' is the wordplay.
'out of' indicates an anagram.
'breath' with letters rearranged gives 'BERTHA'.

(Other definitions for bertha that I've seen before include "collar" , "Woman's name" , "big woman?" , "The bar (anag.)" , "Girl's name - big German WWI gun" .)

I've seen this clue in the Evening Standard.
