No matter what I wear they must change (6,3)

I believe the answer is:

either way

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

'no matter' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'i wear they must change' is the wordplay.
'must change' indicates an anagram (I've seen this in other clues).
'i'+'wear'+'they'='iwearthey'
'iwearthey' anagrammed gives 'EITHER WAY'.

'what' acts as a link.

Can you help me to learn more?
