Scales up? (5)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">scales up?</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for libra that I've seen before include "Someone born between September 23 and October 22" , "The Scales in astrology" , "Person born under Scales sign" , "Seventh sign of the Zodiac" , "Constellation near Virgo" .)
