Working at fair wearing skimpy skirt, or something even skimpier (8)
I believe the answer is:
monokini
'something even skimpier' is the definition.
I can't judge whether this defines the answer.
'working at fair wearing skimpy skirt' is the wordplay.
'working' becomes 'on'.
'at' means one lot of letters go next to another.
'fair' becomes 'ok'.
'wearing' means one lot of letters goes inside another.
'skimpy skirt' becomes 'mini' (mini skirt).
'on'+'ok'='onok'
'onok' put inside 'mini' is 'MONOKINI'.
'or' acts as a link.
(Other definitions for monokini that I've seen before include "Skimpy garment" , "pair of nifty briefs?" , "Small beach garment" , "Swimsuit" .)
