The ultimate in glamour, wearing something black and pink (5)
I believe the answer is:
coral
'pink' is the definition.
(coral is a shade of pink)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for coral that I've seen before include "It seems like rock" , "Basic material of South Sea islands" , "certain islands" , "Reef-forming skeletons" , "rock, perhaps" .)
