If you’re having a purple-themed wedding, you’ll want to shop for purple tuxedos, suits, ties, vests, and cufflinks. Grooms can wear purple if they want. Purple may not be the color some guys would choose, but if the groom wants to wear purple, there’s no reason he can’t. If the groom would rather not purchase a tuxedo, he could rent one instead. Depending on how formal your wedding will be, there’s the option of wearing a purple suit, too.
