In a lime green barely-there mesh dress and towering silver heels, the 22-year-old hopes to bring drag into the mainstream with regular performances in Hanoi, a conservative capital better known for its colonial charm than men in sequined minis.
"If we dare to be pioneers, soon this art will be accepted in Vietnam," Betty told AFP before a show Saturday that stirred up crowds with renditions of hits by Whitney Houston and Alicia Keys.
The drag night started as a weekly viewing party for the hit TV series "RuPaul's Drag Race" and quickly transformed into a show of its own -- drawing a handful of men in drag to the stage for punchy lip-sync performances.
Organiser Tamah Lake said it's the only event of its kind in Hanoi.
"It's brought it more into the open... I think it's becoming slightly more mainstream and slightly more well-known," said Lake, not herself a drag queen, who works as a teacher during the week.
The drag queens who turn out for her Saturday night parties say they have few places to perform in a city where cross-dressing is almost unheard of, unlike in the West where starlets like RuPaul -- the drag queen mother -- have helped to popularise it.
"In Vietnam, there are drag queens that have been active for a long time but have not been acknowledged. This show helps more people know about our art," said Betty, who started the five-member drag group "Victeam" in Haiphong, east of Hanoi.
Communist Vietnam is seen as relatively progressive on LGBT issues -- the one-party state decriminalised gay marriage celebrations in 2015, although it stopped short of full legal recognition for same-sex unions -- and the government is currently drafting a transgender law to allow legal gender changes.
But cross-dressing can help to boost tolerance, according to Vuong Kha Phong, LGBT rights programme officer at Vietnamese NGO iSEE.
"Drag queens being out there performing helps tremendously in getting people to know and be more comfortable with diversity," Vuong told AFP.
Though the drag scene is still just emerging in much of Vietnam, cross-dressing has historic roots: the centuries-old ritual of "Hau Dong" requires mediums to dress as the opposite sex to channel spirits.
Still, when it comes to modern cross-dressing, some drag queens face pushback from the community for blurring gender norms.
First-time performer Za Za Zellia hopes the drag show will help to sway conservative attitudes.
"Hanoi is really traditional, they don't hate (drag) but they don't approve of it at the same time," the 25-year-old told AFP, after debuting in a Gatsby-inspired sequined look.
"This just tells people it's alright, it's completely normal," Za Za said after the show, a huge white feather emerging from a wig of thick black curls.//AFP
