Looking at that style of hair, you probably would want to style the wig with full bang mid wig pulled back. Something like this one, http://kingdom-arts.org/LeTigreShort.html
That has enough bangs to slit back. You probably need to spray, glue and/or trim the wig.
It costs lesser if you do it that way. Unless you want to invest in something like http://kingdom-arts.org/Cady.html
since it limits how much you need to style.
If you can't style it yourself you can always try some members on this website who know how to style wigs who take commission, like Sonteen and a couple of others if you search for it. You can always browse in our wig section too for some examples of different wig stores. The database just for people's reviews on wigs and sample. http://www.acparadise.com/acp/wigs.php
Hope that helps a little!
