Article in English: Your appearance makes an impression on everyone you meet.  This rule applies to any girl that you want to impress.  You don't have to wear a suit to make an impression, but you will have to wear clean and sensible outfits.  Try evaluating what your clothes say about you to judge if you are making a good impression.  Make sure your clothes are clean when you wear them. Check to make sure your clothes fit well.  Clothes that are too big or small may give you an odd appearance. Make sure your clothes match or present an image that you think is appropriate. A huge part of impressing a girl you like is by practicing good personal hygiene.  Chances are, if your hygiene is lacking, you may actually make the wrong impression when being around the girl that has your interest.  Keep some of these basic hygiene tips in mind to help you make a good impression:  Take a shower everyday. Wear deodorant. Brush your teeth at least once a day. Keep your fingernails trimmed. Your body language says a lot, without you ever having to speak a word.  Take a careful look at your body language when you are near the girl you like.  Make sure to keep these tips in mind when you are trying to say the right thing with your body language:  Don't hunch your shoulders down or forward.  Have them naturally pushed back. Stand up straight at all times, keeping your head up. Avoid slouching whenever sitting down. If you are nervous or guarded when you are near a girl you like, you're body language might demonstrate those feelings.  Any kind of “closed off” body language will prevent people from approaching you.  Taking an open and relaxed stance when standing or sitting can help show your confidence and send the message that you are open to interacting with her.  Keep some of these tips in mind when trying to maintain open body language.  Make sure you stand so that you are directly facing her. Keep your arms down, at your sides. Avoid crossing your arms or otherwise blocking the other person off.
