Summer clothing small — take it off? (8)
I believe the answer is:
sundress
'small take it off?' is the definition.
I can't tell whether this definition defines the answer.
'summer clothing' is the wordplay.
'summer' becomes 'sun' (I can't justify this - if you can you should give a lot more credence to this answer).
'clothing' becomes 'dress' (dress is a kind of clothing).
'sun'+'dress'='SUNDRESS'
Can you help me to learn more?
(Other definitions for sundress that I've seen before include "evident when the heat is on" , "Summer frock" .)
