In the first episode, Beth is wearing a light grey dress with a collar. Fast forward to the last episode, during the last match, she is seen wearing the same color dress that also happens to have a collar. "In episode one, Beth is wearing a dress that her mother made for her, tenderly embroidered with her name. The colour of this dress represents Beth’s sense of ‘home’. We wanted to create a moment when she could once again come ‘home’, which is why she is wearing the same colour dress in her final tournament in Moscow—the dress she is wearing when she is winning. We wanted to use this colour to show that she finally feels confident and that her mother is with her," the show’s costume designer Gabriele Binder revealed in an interview with Vogue.
