I went to Rondavous Lingerie Boutique at Far East Plaza , that is owned by two famous sisters who are singers , they called themselves 2R duo.
The shop is currently managed by Ronda Wong , the youngest sister of 2R duo.
The shop sells mainly g-string, camisoles, and other lingeries. The prices are generally over S$200.
Here is the video of 2 R duos.
