While Haruhi is one who claims she'd rather be doing the capturing than being captured, there have been times when she's rather gotten into it, so drawing that attitude out of her requires some kinky ties. For a more casual approach, her legs and butt are great features so any outfit that focuses on them is a good choice. If she falls into the right mood, she'll eventually stop fighting and start putting on a good show, especially if she has something enjoyable to watch at the same time. The best way to handle Haruhi is to be unpredictable. It will not only catch her off guard but also be something she secretly approves of.
