Check the requirements
At the start of each catwalk, you will be told what you are dressed for. Make sure you pay attention to this, because if you wear something that doesn't fit the theme, you will be penalized. The theme remains as you walk, so keep checking to make sure you are wearing the right clothes.
Choose the item that makes the most sense
More often than not, it will become quite clear which item of clothing you should wear. Take a look at the options and choose the one that best fits the catwalk theme. Don't wear sneakers if you're destined for a nightclub, for example. Make a sensible decision and you will do well.
Ignore what your opponents are doing
It may be tempting to look at your opponents and see what they are doing. It makes much more sense to ignore it completely. Especially in the early stages, they will do many things. Focus on your own clothes and you will have a greater chance of being successful.
Swap if something goes wrong
The choices you make are not final until you move to the next section of the catwalk. If you pick a style or outfit and you think it's wrong, you have time to swap out one of the other two types of clothing. But think quickly, because you won't have much time to make changes.
Don't worry about cash
You can't really spend the coins you collect on anything, so don't worry about increasing your catch by watching videos. You will unlock new clothes just by playing, so focus on getting them and don't worry too much about money.
