One of the things that make a fashion designer great is the way that they can play with textures, patterns, and colors. It is not simply that they pair different patterns and colors together in new ways, it is that they are taking something that you would not think go together and made it flow seamlessly and look beautiful. If you are trying to mimic a fashion designers line on the runway by mixing patterns and colors there are some easy to follow rules that will ensure that you look stylish and not loony.
First, remember that all neutrals, no matter the patter, go together. You can also pair a neutral with any pattern or color. If you are wearing a crazy print with a bold pattern or a bold color, do not pair the pattern with the another pattern or print. Pick a color from the pattern and wear something within the same color line. You could also pair any pattern or color with a neutral.
Second, many people think that an all over print will make them look large and are therefore afraid to try to wear a print or pattern. It is always important to remember that prints and patterns will not make you larger as long as you are wearing the appropriate fit. Fit will account for more than any pattern or color. A print can be more flattering than black as long at the piece fits you correctly. Never be afraid to try a print or pattern. These are great piece to have in your wardrobe that will really stand out.
