Skirt put on last of all to hold a service (6)
I believe the answer is:
dirndl
'skirt' is the definition.
(dirndl is a kind of skirt)
'on last of all to hold a service' is the wordplay.
'on' says to put letters next to each other.
'last of' suggests the final letters.
'to' becomes 'did' (I can't explain this - if you can you should believe this answer much more).
'hold' indicates putting letters inside.
'a service' becomes 'RN' (abbreviation for Royal Navy).
The final letter of 'all' is 'l'.
'did' going around 'rn' is 'dirnd'.
'l' put after 'dirnd' is 'DIRNDL'.
'put' acts as a link.
Can you help me to learn more?
(Other definitions for dirndl that I've seen before include "Skirt that's tight at the waist and wide at the bottom" , "Alpine peasant woman's dress" , "Woman's dress in Tyrolean style" , "Tyrolean skirt" , "Dress with close-fitting bodice and full skirt" .)
