Wearing 36I, (US), calculator says 36FF UK

47 yo cis female, no pregnancies or breast surgeries: 9 years ago I had a gastric bypass resulting in weight loss over 100lbs, at my highest I think I was wearing at 44H

Measurements. Underbust loose: 36 in Comfortable snug: 35.5 in Tight: 33.5in

Bust: standing 41 in Leaning forward at 90 deg: 46 in Lying down: 44 in

I ordered my last few bras off Amazon many of them like weird brands from China: one I’ve worn is Delimira which was ok but over time became a bit flimsy. It looks like my breast projection is shallow (they’re fairly flat when I’m not in a bra)

Thanks for reading
