1.The first rule in print mixing is to make sure that one colour repeats in every piece of the outfit,for example navy paisley with navy,red and white plaid.
2. Then,mix large or bold prints with smaller prints to make a balance.
3.Use accessories to do the mixing and make the outfit look more interesting.
4.Mix neutral prints with prints that pop.So,choose a neutral print and try to pair it with a louder and more colorful one.
You can also mix practically the same prints with each other.
