Don't Miss:

Glee‘s hit first season comes to a close tonight, and it looks like the highly-anticipated Regionals will be a competition in both song and style. “[The girls in] New Directions wear retro-style gold brocade dresses by Betsey Johnson with ’60s-inspired hair and makeup, in a nod to the ’60s girl groups,” the show’s costumer Lou Eyrich told us. “The guys wear color-coordinated shirts and ties.” As for their musical nemeses Vocal Adrenaline? “[They] wear very flashy and bold fuschia-and black-sequined dresses, which really pick up the light when they dance,” she said. “They perform an amazing rendition of Queen’s ‘Bohemian Rhapsody.’” There’s a medley of songs by ’80s rock group Journey, and we can also expect to see a few familiar faces: “Olivia Newton John and Josh Groban are back, but they don’t sing,” Eyrich revealed. “And Quinn’s mom shows up.” She also warned that Gleeks should watch the finale with tissues on hand. “I remember crying when I first read the script,” said Eyrich. “Tears were shed by many during shooting.” Watch the clip above of Rachel (Lea Michele) and Finn (Cory Monteith) singing Journey’s “Faithfully” from tonight’s big Glee finale.
