Is the catwalk allways the same? And if why does it newer change?

When models walk they always have amazing posture. u need to keep your head up as if someone wuz pulling u straight up with a string. U also have to have attitude. So the 3 most important thing to remember when ur walking down a startbaan, start-en landingsbaan is 1.) posture, 2.) attitude, 3.)timming and rythem!
