Only G cup bra that I found on the market

Only G cup bra that I found on the market focus, however, take one or even two sizes larger than your waist, I'm doing 90 G so I took the 95 G having big problems with a great brand with Sport a bra overpriced (5 times more expensive than this one) because I could not close it behind, or the 95 G if it suits me to the last notch staples is just right, if I had known I ' would have taken two sizes above (100 G), but it keeps perfectly without gainer or compress, the colors are beautiful I'll even put like jackets with nothing on it for fitness. The fabric is light enough but still perfectly maintained when one jumps or short. I put the note 5/5 despite it size a little small and there needs to be because the straps are lined with a silicone material such as silicone or (?) That keeps them perfectly in place without slipping.
I will redeem for not being out because as I said I had never found cap "G" in commerce either in France or elsewhere, and this time I will take two sizes above what I do (100 G 90 G)
