Hello,<br/><br/>Can you use "each other" to refer to more than two things?<br/><br/>For example,<br/><br/>Blue shirts and red shirts complement each other.<br/><br/>Can you use "each other" to refer to many shirts like the above?<br/><br/>Or does it have to be "a red shirt and a blue shirt complement each other"?<br/><br/>thanks.
