Similar wigs

There is no similar wig in terms of this colour, however, there are three wigs that also have one colour and the same style, namely the pink with a fringe, platinum blonde with bangs, caramel with a fringe wigs and these could be a fair substitute in terms of single coloured wigs.  The blue & blonde wig could also be most similar in terms of both wigs having a blue colour - though the blues do not match.
