Inscription on the back of the photo is washed out, the only readable info is the date taken - January 12, 1940, and the name it is addressed to - Lelang.
Her 1940s dress has a tight bust line and curved standing collar. There's the puff sleeves with 2 inch cuffs, floral embroidery embellishes the bodice and waistline area and the skirt is a pleated A-line. Skirt length is just inches below the knee. She is also wearing leatherette open-toe shoes with self-tie closure.
For a 1940s studio portrait, her dress looks very utilitarian yet modern. Her face is more on the Chinese side than Malay.
