The event attracted large numbers of Vietnamese people, both men and women of all ages, with the youngest 5 years old, and the eldest, 78.
As well as the fashion show, contestants attended two Q&A sessions on Vietnamese traditional outfits and customs.
Participants had the opportunity to enjoy music and dance performances and taste traditional Tet dishes during a cooking contest.
This was the second time the overseas Vietnamese community in Little Saigon held such an event and once again it received huge applause from audiences.
