Theoretically, do slim girls have big breasts?

Yes I am like this, with thin arms and thin legs. I have been like this since the third grade. My measurements are 85, 58 and 88, mainly because my mother is like this, and my aunt is also a sauce purple. Judging from the genes of both parents, I am doomed to be a sauce purple. But the height is only 16 1, the weight is about 90, the collarbone is obvious, and the baby face.
