Blouse or halter
I believe the answer is:
top
I believe this is a double definition.
'blouse' is the first definition.
(I've seen this in another clue)
'halter' is the second definition.
(I've seen this in another clue)
(Other definitions for top that I've seen before include "Most successful" , "Best" , "cap and > sweater" , "Highest point or position" , "Apex; child's toy" .)
