I'm a little stuck... Click here to teach me more about this clue!

'inelegant' is the definition.
('graceless' can be similar in meaning to 'inelegant')

I cannot understand how the rest of the clue works.

(Other definitions for graceless that I've seen before include "clumsy" , "Lacking elegance" , "Indecorous" , "Awkward" .)

I've seen this clue in The Independent.
