Bonobos, the upscale men’s clothing retailer known for its well-fitting pants, is expected to be acquired by Walmart in the next few months. This pairing is not as odd as it may seem: Walmart has been diversifying its holdings with the purchase of several trendy e-commerce sites — including Shoebuy, Moosejaw and ModCloth — that give it access to fashion-conscious customers who likely wouldn’t be caught dead buying clothes at Bonobos is a web-based business with a handful of physical stores, including the one at Westfield Montgomery Mall, where customers can try clothes in person but still make their purchases online. It’s unclear whether this acquisition would ultimately lead to Bonobos clothes being sold on Walmart’s website.
