Wear Different Textures

Flirting and being seductive is NOT about revealing your entire body. In fact, it's often seen at strip-clubs that the guys there are more interested in the waitresses, because they are still clothed and are therefore "real girls". Flirtation is about those gentle give-and-takes between two individuals who want to learn more about each other.

So avoid the mini-clothing and instead go for clothing that flatters you and is also interesting. Wear a long-sleeved velvet shirt. Wear a long skirt made up of different fabrics. It'll give him an excuse to touch the material and see what it's like. All humans are curious about touch, and are drawn to new sensations. When you offer new, interesting touch sensations for him, it's an easy way to get him closer.
