Bands' accommodation good for Queen (7)
I believe the answer is:
garters
'bands'' is the definition.
(garter is a kind of band)
'accommodation good for queen' is the wordplay.
I cannot really see how this works, but
'good' could be 'g' (abbreviation) and 'g' is present in the answer.
'queen' could be 'er' (abbreviation for Elizabeth Regina) and 'er' is found in the answer.
The remaining letters 'arts' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for garters that I've seen is " Bands to hold up stockings or sleeves".)
