The distance of the show on Runway is too far, it's better to actually visit department stores and ask the salesladies what color would be more grounded.
Basically, the advertising image of European and American styles are relatively conceptual. If you want to replicate them, you probably need an occasion like a Gucci fashion party so that people won't feel it's too formal.
You can choose one or two popular colors or techniques from a look, highlight the key points, and that's trendy enough to express your intention.
As for the Japanese style advertising image, it follows a practical and approachable route. You can target the characteristics of your own facial features and ask the saleslady to demonstrate step by step in a one-on-one teaching session. Then, according to the occasion needs, use the subtraction method, such as reducing a few steps and using lighter hand with colors, and you'll get it right!
