You've hat and dress sorted for spring blow-out? (6,7)
I believe the answer is:
shrove tuesday
'spring blow-out?' is the definition.
I can't judge whether this definition defines the answer.
'you've hat and dress sorted' is the wordplay.
'and' says to put letters next to each other (I've seen this in other clues).
'sorted' indicates anagramming the letters.
'youve'+'hat'='youvehat'
'youvehat' after 'dress' is 'dressyouvehat'.
'dressyouvehat' is an anagram of 'SHROVE TUESDAY'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for shrove tuesday that I've seen before include "Pre-Lent feast day" , "Pancake Day" .)
