The two girls in this short clips are wearing a schoolgirl-style uniform that is quite common in Thailand and other parts of Southeast Asia.
The outfit consists of:
A white short-sleeved button-up blouses: Both tops are neatly tucked in, with a slightly fitted cut that gives a polished and clean look. The buttons and collars make the outfit formal and academic in appearance.
A black skirts: Each girl is wearing a black skirt, short in length, which adds a more modern and fashionable touch to the otherwise traditional uniform. One skirt features a small front slit, giving it a stylish edge.
