Women of SW please help me buy the right bra size!!

I bought this one (95D) as I thought it was my size. But the middle section in front is not towards my skin. It's in the air and looks like it's too small. So what is my size then? Is it 95E or 100D or how does it work? It's already a bit big in the cup but C is definitely too small.


I was to a store and tried bras, but she who worked there wanted me in a 90C cup and it felt like a straight jacket and too tight everywhere. Either she had no actual expertize or I just prefer the bra more loose and rather a big big than too small.
