Designed by Michelle Clapton, the costumes are every inch the Seventies sartorial dream, with metallic platform boots, star logos, denim dungarees and - of course - tiered flares.
Starring Lily James as a young Donna Sheridan - with Meryl Streep returning as the key role in her later years - we hear how the young star felt in costume.
"I just looked at all the outfits that Michelle had picked out and I just was like 'YES!'. And she totally got, and understood, Donna."
"I put [the dungarees] on and just went 'Oh yeah! I feel like Donna!'"
Jessica Keenan Wynn, who plays a young Tanya, admitted that "the costumes make it!'.
"Once we put on the costumes I really think it informs your character."
"It's so fun, it's so girly, it's so flirty...".
