Lois came out in her underwear (8)
I believe the answer is:
camisole
'underwear' is the definition.
(I know that camisole is a type of underwear)
'lois came out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'lois'+'came'='loiscame'
'loiscame' with letters rearranged gives 'CAMISOLE'.
'in her' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for camisole that I've seen before include "clothing" , "Underbodice with shoulder straps" , "Item of lingerie" , "Top" , "nightwear" .)
