For reference these are the bras I bought:
(1) Chantelle Rive Gauche 3286 T-shirt - cups fit well, but the gore wasn't wide enough so it didn't sit flush to my chest.
(2) Fantasie 4520 Balconette - It fits, but I don't think I love the shape of it.
(3) Wacoal Fine Form - I kept this one, it fit really well surpisingly, but it is super matronly
(4) Chantelle C Natural Seamless - I muffin topped out of this one
(5) Fantasie 4510 Seamless Smoothing Underwire - Gore was flush, but I didn't fill out the cups
(6) Panache 'Envy' Underwire Stretch Lace Bra - Gore was flush and I filled out the cups and the wires fit (oddly enough), but I didn't love it.
(7) Freya 'Rapture' Plunge Bra - I don't feel like the wires or the cups encapsulated my breasts correctly.
(8) Natori Feathers Contour Underwire - Ok. Ok. I know everyone hhhaaattesss this bra. Listen, this bra is totally in my wrong size (34G UK), but I fucking love it and the wires encapsulate my breast tissue, the gore lays flush, I'm not muffin topping out of hte cups. I LOVE IT and I'm keeping it, even though I know it is totally wrong for me.

I don't know, I know for sure I am a 34FF(UK) from the calculator, I know I am full on bottom, and I know I have very shallow breasts bc my breast tissue goes almost all the way up to my clavicles and I don't project very much. Maybe I am wrong about having shallow roots? I am just so fucking frustrated right now.
