Curly and very short in style (4)
I believe the answer is:
wavy
'curly' is the definition.
('wavy' can be similar in meaning to 'curly')
'very short in style' is the wordplay.
'short' says to take the initial letters.
'in' indicates putting letters inside.
'style' becomes 'way' ('way' can be a synonym of 'style'**).
The initial letter of 'very' is 'v'.
'v' inserted into 'way' is 'WAVY'.
'and' acts as a link.
(Other definitions for wavy that I've seen before include "Curly (hair)" , "Sinuous" , "full of bends" , "Rippled" , "Undulating" .)
