The average bra size has gone up because the average weight has gone up by a ton in the US. Asians also typically have a genetic tendency toward smaller boobs, but that obviously isn't true for every last asian woman. Long story short, 36B is a perfectly normal bra size for a 15 yo girl, asian or otherwise. I wouldn't worry too much if I were you. Maybe try to follow a healthy diet that encourages good hormone production, and wait a few years. It's pretty likely that you have one or two years of puberty left, depending on when you started.
