As a general rule of thumb, print overkill is best avoided. If one component of your outfit features a vibrant print, it’s best to keep the rest of your look a plain and simple affair, so opt for clean-lined separates.
One strong pattern is enough of a statement by itself. For those of a more daring disposition, clashing prints can work; just make sure the prints contrast but complement each other by pairing motifs that differ either in tone or pattern, but not both.
