Summarize:

These little grooming behaviors are good indicators that he's interested in you and he wants to look his best. He may tug at his socks, smooth out his lapels or tie, button and unbutton his jacket, or fidget with some other part of his attire. Take it as a good sign if he can't seem to stop messing with his clothes. If you notice him doing this, now might be a good time to pay him a compliment about his outfit. Try saying something like, "I love the color of that tie. It really brings out the green in your eyes." Along with frequently touching his clothing, he might also stroke his hair, mess it up, stroke his beard or moustache, or touch his face. He may not even be aware that he's doing this, but it's a good indication of his interest if he does. If you spot him doing these things, try paying him a compliment, such as by saying, "I love how you style your hair. It's so sleek!" Or, "Your beard is so luxurious! May I touch it, please?" Talking with hand gestures is often a sign of confidence, but it can also indicate interest in the person you're talking with. If he's making huge hand gestures, it's sort of like he's saying, "Look at me!" He may be doing this to ensure that you notice him. Try mirroring his hand gestures by using your hands when you talk as well, but only if you normally do this. Don't try using hand gestures if it doesn't come naturally to you. If he touches you in subtle ways, these can be even strong clues that he might be interested. It's unlikely that he'd touch you if he wasn't interested, so pay special attention to any contact he makes with you. Some subtle ways he might touch you include: Standing close to you so that his body brushes against yours Touching the small of your back or your arm Brushing your hair out of your eyes Reaching out to hold your hand
See if he fidgets with his tie, socks, or buttons. Watch for him to stroke his hair, face, or facial hair. Look for big hand gestures when he's talking. Pay attention to any subtle touching.
