Just coming up, link for woman's garment (7)
I believe the answer is:
nightie
'woman's garment' is the definition.
(garment worn by a woman at night)
'just coming up link' is the wordplay.
'just coming up' becomes 'nigh' (nigh can mean approaching or coming up).
'link' becomes 'tie' (synonyms).
'nigh'+'tie'='NIGHTIE'
'for' acts as a link.
(Other definitions for nightie that I've seen before include "Lingerie worn in bed by women" , "Lingerie item" , "Woman's bedwear" , "Bedtime habit" , "Garment for ladies" .)
