The general rule to mixing and matching patterns is to have each pattern the same size. When wearing all the same pattern, they should gradually go from big to small. If everything is the same size, it makes the outfit look too busy, which in turn, makes it difficult to focus on one item.

For example, a windowpane suit will have the biggest windowpanes, the shirt on the other hand, will have smaller panes. To top it off, the tie's print should be smaller than the shirt. Mixing different patterns can be tricky and can easily be messed up.

 

The suit doesn’t always have to be the largest, it can be the tie or the shirt sometimes. It’s all about creating different proportions that make everything work.
