Fashion to follow as an alternative (6)
I believe the answer is:
tailor
'fashion' is the definition.
(I know this)
'follow as an alternative' is the wordplay.
'follow' becomes 'tail' (both can mean to chase or pursue).
'as an alternative' becomes 'or' (I've seen this in other clues).
'tail'+'or'='TAILOR'
'to' is the link.
(Other definitions for tailor that I've seen before include "One makes fitted clothes" , "Cut" , "man of the cloth" , "person before soldier and sailor in list" , "Maker of clothes, men's mostly" .)
