Women's undergarments -- they may cause embarrassment (8)
I believe the answer is:
bloomers
I believe this clue is a double definition.
'women's undergarments' is the first definition.
'they may cause embarrassment' is the second definition.
(bloomer is an old-fashioned term for a mistake)
(Other definitions for bloomers that I've seen before include "made by clothing manufacturers" , "Undergarment" , "Flowery types" , "Mistakes, underpants, loaves or flowers" , "Old underwear" .)
