Fashionable and stylish, but completely lacking in grace (9)
I believe the answer is:
inelegant
'lacking in grace' is the definition.
(I've seen this in another clue)
'fashionable and stylish' is the wordplay.
'fashionable' becomes 'in' (in can mean fashionable or trendy).
'and' means one lot of letters go next to another.
'stylish' becomes 'elegant' (both can mean fancy or ornate).
'in'+'elegant'='INELEGANT'
'but completely' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for inelegant that I've seen before include "Lacking refinement" , "ungainly" , "Unpolished" , "far from chic" , "laboured" .)
