Inspired by his Irish roots, Conor McGregor’s walkout look was created by bespoke menswear designer David August. His cape was an Irish flag, a piece the Irish boxer hasn't worn in a professional fight since 2005. He paired it with white boxer shorts made from high-tech fabric embossed with leather side panels. The logo-emblazed waistband was the perfect promo for his upcoming fashion line with the designer, dubbed August McGregor. In the opposite corner, Floyd Mayweather Jr. wore a custom Philipp Plein ultra-luxe crocodile robe--and a full-face ski mask, natch.
