Regularly removed attire? (3)
I believe the answer is:
tie
'regularly removed attire?' is the definition.
'tie' can be an answer for 'attire?' (a tie is an item of clothing). I am not sure about the 'regularly removed' bit.
'regularly removed attire?' is the wordplay.
'regularly removed' indicates alternate letters (letters removed at regular intervals).
The alternating letters of 'attire' are 'TIE'.
Can you help me to learn more?
(Other definitions for tie that I've seen before include "Fasten; level game" , "Drawn score" , "Affiliation" , "Bond; neckwear" , "Bond > girl wearing this? Unlikely" .)
