If a girl, whose attention you want to achieve is dressed with style and taste you cannot afford to look sloppy or boring. Scroll through men's fashion magazines and buy a few new things as you equip yourself with fashionable accessories. All of this will not only make you more attractive and smart but it will also give you a lot of confidence.
Keep track of things she likes. Draw conclusions from her personality. For example, if you have found a girl in a music store, see which genre she listens to. After getting the necessary information about the particular song or album, try to talk to her.
Let the girl feel secure each time you look at her. Even the most emancipated feminist will be nice to you if the right approach is taken. Never come on too strong as it makes you look desperate. Just initiate a general conversation that is light and quite possibly funny as well.
Self belief is the key before thinking about busting a move on a girl regardless of your physical appearance, ethnicity and economic status. Be bold and confident, she must see you as a strong man, with whom she can be secure.
Buy flowers, gifts and give compliments. Girls like to feel unique and special as this is what awakens a feminine quality in them. Over time, she will look at you with admiring eyes.
