Unkempt educationalist teased about leggings, principally (10)
I believe the answer is:
bedraggled
'unkempt' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for bedraggled that I've seen before include "Dishevelled" , "Very untidy" , "Unkempt" , "Wet and dirty" , "muddy and dripping" .)
