Stylish Barbie accessory: meat! (7)
I believe the answer is:
chicken
'meat' is the definition.
(I know that chicken is a type of meat)
'stylish barbie accessory' is the wordplay.
'stylish' becomes 'chic' (similar in meaning).
'barbie accessory' becomes 'ken' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'chic'+'ken'='CHICKEN'
Can you help me to learn more?
(Other definitions for chicken that I've seen before include "Yellow - young fowl" , "Informally cowardly like domestic fowl" , "(Yellow?) bird" , "Cowardly (colloq.)" , "Prov. cowardly bird" .)
