Hello Doctor, It was around 3 years back, when I was 18 years old, my bra size was 80cms.(n 80 has remained cost. For three later years) Later, in the next one and a half year, the size got increased to 85 Cms. Which was still ok. But the size 85 cms, lasted only for few months (5 to 6), and now it's 90 cms. Which is really big for a gal of my age. (20 yrs.) This big size doesn't give my body a good appearance.
