What do you wear to a polo match? Nashville costume designer Susie DeSanto had all the answers and more when InStyle caught up with her this morning. Both Rayna (Connie Britton) and Juliette (Hayden Panettiere) headed to the races in last night’s episode—flirting with the high society elite of Tennessee? Check! “We shot some of the polo footage a week before we shot the episode, so I got a glimpse of the real thing,” DeSanto told InStyle. “Having a good set piece is so important, I knew right away I wanted a big broad-brimmed hat for Connie!” DeSanto worked with New York hat designer Christine A. Moore, who custom designed both ladies fashionable headpieces.
