Halloween is a celebration observed in many countries on Oct. 31, the eve of the Western Christian feast of All Hallows' Day as a way to remember the dead, including saints (hallows), martyrs, and all the departed.
Children also flocked to Hang Ma Street to buy Halloween costumes based on their favorite characters.
In the photo is a child dressed as a Roman warrior in a costume that costs about VND400,000 ($16).
Restaurants and street-side stalls along Ta Hien Street are packed on Sunday night.
Ta Hien is only about 200 meters long, connecting with Luong Ngoc Quyen, Ma May and Hang Bac streets and home to bars, beer stalls and restaurants, attracting tens of thousands of weekend revelers.
Ly Quang Dieu (2nd, R) and his friends took six hours to do their own makeup in order to perform on Nguyen Hue pedestrian street.

Each outfit costs from a few million to tens of millions of dong.
Face painters offer their services on Nguyen Hue pedestrian street with prices ranging from VND50,000 per turn.
