Bound to the old patterned garment (6)

I believe the answer is:

tiedye

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

'patterned garment' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'bound to the old' is the wordplay.
'bound' becomes 'tied' ('tie' can be a synonym of 'bind').
'to the old' becomes 'ye' (resembles a historical spelling of 'the').
'tied'+'ye'='TIEDYE'

Can you help me to learn more?

(Another definition for tiedye that I've seen is " patterns on cloth by this method".)

I've seen this clue in The Daily Express.
