When Jeanne Foley got married, her mother blew $500 on two ill-fitting tuxedos for Jeanne’s brothers to wear just once, at the ceremony. The Under Armour veteran knew she could do better. In 2016, she launched the Groomsman Suit with childhood bestie and Sloan School of Management grad Diana Ganz. The direct-to-consumer startup sells tuxedo separates for under $200--much less than traditional rentals. But Foley says the real key to the company’s success has been its “amazing service.” Orders ship within 48 hours, and returns and exchanges are free. As a bonus, the Groomsmen Suit will ship new items before they’ve received the originals. The group-ordering service even nudges groomsmen by email to get it together and order their tuxes--it may be the best thing that’s happened to weddings since candy stations. --Jill Krasny
