The pair maker feature is something you might be interested in learning more about and using if your website is dedicated to fashion clothing.
The website user's first decision should be whether to buy a pair of jeans or a shirt or t-shirt he prefers.
The other half of the pair will be displayed so that the user will have a good understanding of whether the chosen products go well together.
It is essential to give this function a try once. It is indirectly provided to give the conventional salesperson more ways to sell.
