They may hide tights, ironically (6)
I believe the answer is:
slacks
'they may hide tights' is the definition.
(tights may be worn under slacks)
I can't explain the remainder of the clue.
(Other definitions for slacks that I've seen before include "bags" , "Pants for casual wear" , "casual attire" , "Things to wear" , "Avoids work - trousers" .)
