Get anorak from Designer Delights (4)

I believe the answer is:

nerd

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

'get anorak' is the definition.
I can't judge whether this definition defines the answer.

'from designer delights' is the wordplay.
'from' indicates a hidden word.
'NERD' is hidden in the letters of 'designer delights'.

Can you help me to learn more?

(Other definitions for nerd that I've seen before include "Foolish or annoying person" , "Studious bore" , "Boring person" , "Boring, trivia-obsessed type" , "one that's overly cerebral" .)

I've seen this clue in The Sun.
