Walking like a catwalk model is simple to start; however, it is an art to perfect. 
Here there are some steps to follow: 

1) Set your chin facing slightly down

Keeping your chin facing slightly down will let the audience see more of your face and it will add angle to your face and will help lend you a little bit of attitude. 

2) Keep your eyes focused on something ahead of you

Keep your eyes fixed on a point, and do not look around you. Stay concentrated on where you are going, and look alert and at attention.

3) Stand up straight!

Keep your shoulders slightly back, and stand up as straight as you possibly can. This posture is what is going to sell the model presence the most, even if you are not actually tall like a model.

4) Place one foot in front of the other and walk with long strides

It will allow your hips to swing from side to side in that classic model way. 

5) Allow your arms to hang at your sides, and keep your hands relaxed

You do not need to swing your arms quite as much as your body will naturally. Let your arms hang and swing only slightly. This will make you look cool and composed as you walk down the catwalk. Likewise, keep your hands relaxed so that they are loosely cupped and slightly open. 

6) Practice walking with your heels on

7) Get a rhythm down, and keep it consistent with your step

Listen to music with a strong beat that has an attitude that you like while you are practicing strutting with your heels on. 

8) Strike your pose

And then you are Ready to be the next queen of Miss Europe Continental 2020.
