The plait is not defective - this is the nature of a fishtail plait. This feature adds to the 'authenticity' of this item as a purely smooth plait would not blend into your own hair. Work the fishtail braid trend like Blake Lively or Rochelle Wiseman by adding this chunky fishtail braid, wear high on the head for a glamorous take on the look or more low slung for a casual cool look.
