Sophisticated date, yes -- so I go steady (4,4,2)

I believe the answer is:

easy does it

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

'sophisticated' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'date yes so i go steady' is the wordplay.
'date yes so i' can be anagrammed to 'EASY DOES IT'.
Though, I am unsure how this is indicated.

Can you help me to learn more?

(Other definitions for easy does it that I've seen before include "Don't stress yourself!" , "Gently" , "relax" , "Take your time" , "Be careful" .)

I've seen this clue in The Telegraph.
