Travel to three points to obtain frocks (5)
I believe the answer is:
gowns
'frocks' is the definition.
(gown is a kind of frock)
'travel to three points' is the wordplay.
'travel' becomes 'go' (synonyms).
'to three points' becomes 'WNS'.
'go'+'wns'='GOWNS'
'to obtain' is the link.
(Other definitions for gowns that I've seen before include "formal attire" , "Fancy frocks" , "Scholars' robes" , "Long flowing dresses for women" , "Theatre outfits" .)
