Well, I see that wig sold. If you bought it I hope it works out for you. It looks so great long it would seem a shame to cut it, though. If I wanted a medium length, I think I'd have looked for something more that style. The short style you linked to appears to be a professional cut and very different from that wig's cut. I wouldn't try to cut it unless you're a trained stylist. If that's what you want to do, take it to a shop and have a pro cut it for you.
