What an offended person may do, being attached to a dress? (7)
I believe the answer is:
flounce
This might be a double definition.
'what an offended person may do being attached' is the first definition.
The definition suggests a singular noun which matches the answer.
'a dress?' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'to' is the link.
Can you help me to learn more?
(Other definitions for flounce that I've seen before include "Frill; walk affectedly" , "Move with pettish impatience" , "Strut" , "Act impatiently" , "Exaggerated walk" .)
