Head-turning ladies getting tense for a short time (6)
I believe the answer is:
moment
'short time' is the definition.
(moment is a kind of short time)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for moment that I've seen before include "Significance; minute" , "Second, flash" , "little while" , "An instant in time - important" , "Import" .)
