Habit associated with crawling, maybe? (8)
I believe the answer is:
swimsuit
'habit' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for swimsuit that I've seen before include "Bathing-costume" , "female garment" , "Beach costume" , "Bathing attire" , "Outfit for a dip" .)
