Step 1: Posture (姿势)
When walking on the runway, posture is very important. Try to make your body as tall as possible, keeping you back and neck straight. Your head should face straight head of you and should be fairly still, rather than flopping around . Some models also lean back slightly, so that their legs are moving forward before the rest of their body.
Step 2: Legs and feet (腿和脚)
Walk with your feet facing straight ahead of you, rather than turned out to the sides. As you take each step place your foot down in front of the other one, rather than parallel to each other. You can even cross your legs over in front of each other, but take care not to trip yourself. Some models also lift their legs up very high while walking. This is done by bending more at the knee, almost like a horse would, and then placing the foot down quite far ahead to take longer strides.
Step 3: Hips (臀部)
It's a bit of a myth that models sashay their hips from side to side in a very pronounced manner. Although your hips will naturally sway from side to side, it's not usually necessary to force or exaggerate this movement.
Step 4: Arms (胳膊)
What you do with your arms will depend on the type of clothes you're modelling. Although your arms will swing naturally by your side as you walk, as a general rule try to avoid big arm movements or pronounced arm swinging. With some clothes, you might want to put your hands in your pockets to go for laidback and relaxed look.
Step 5: Posing (摆姿势)
When reaching the end of the runway, models usually pause for a moment to show off the clothes. Do this by jutting one hip out to the side, with lots of attitude. If you're wearing a jacket, this is also a good time to slip it off and fling it casually over your shoulder.
