Simply sitting the CEOs of Wal-Mart and Jet.com next to each other shows you just how different the cultures are at the soon-to-be-wed companies.
In preparation for an interview with CNBC's "Squawk Box," Wal-Mart CEO Doug McMillon threw on a pair of jeans, as he tried to channel the vibe of a relaxed start-up founder.
Meanwhile, Jet CEO Marc Lore dressed in a blazer and a pair of slacks, in an effort to look more corporate. It was so out of character that he forgot to wear a belt.
Their wardrobe differences aside, Lore told CNBC Tuesday that the $3.3 billion combination of the two companies, expected to close this year, is a "perfect marriage."
