Twins for example lifted skirt (6)
I believe the answer is:
gemini
'twins' is the definition.
(twins are the symbol of the star sign Gemini)
'example lifted skirt' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'lifted' is a reversal indicator (going up in down clue).
'skirt' becomes 'mini' (a mini skirt).
'eg' reversed gives 'ge'.
'ge'+'mini'='GEMINI'
'for' is the link.
(Other definitions for gemini that I've seen before include "House" , "lot of stars" , "Zodiac sign - the Twins" , "Twins constellation" , "Sign of the Twins ( 6)" .)
