Plastique Tiara Edwards, simply known as Plastique Tiara, is the stage name of Duc Tran Nguyen, a drag queen, performer, hairdresser, and content creator.
Plastique was announced as a contestant on Season 11 of RuPaul's Drag Race, finishing in eighth place.

"Plastique Tiara" comes from the name of the My Little Pony character "Diamond Tiara". Tiara likes both the name and the character, but since a lot of people have "diamond" on their stage names, she chose "Plastique" as hers as an allusion to plastic, a cheap material used to make luxurious Barbie dolls. "Edwards" comes from her drag mother Season 5 and All Stars 2 contestant Alyssa Edwards' last name.

As drag daughter of Alyssa Edwards, Tiara is a member of the "Haus of Edwards" alongside Shangela (from Season 2, Season 3, and All Stars 3), Laganja Estranja (from Season 6) and Vivienne Pinay (from Season 5).

With a strong online presence, a RuPaul's Drag Race legendary alumna as her drag mother, as well as a lot of inspiration from Vietnamese pop stars and Asian culture translated into a flowy fashion feminine style, Tiara was considered to be an early favorite in the competition, later proving that she live ups to the "Edwards" name with her performance skills. During Season 11, she was particularly praised for her polished runway looks, landing Tiara her first (and only) main challenge win in Episode 7, after previously placing in the top for the Legendary Look Challenge and the Monster Ball. Tiara also performed well in the first comedy and acting challenges of the season, placing high in the blockbuster movie challenge and delivering solid performances in Trump: The Rusical and Snatch Game. However, she was criticized by the judges for her reliance on Asian stereotypes, and failed to create a convincing character in Episode 9's improvisation challenge. After losing a lip-sync to Vanessa Vanjie Mateo in that episode, she placed eighth overall.
