Edit 12/6/2020 - apparently it really was just too small. It fits me perfectly now, at roughly 32G UK. So yes, the cup height makes it large on me with my short roots, but sizing down one cup and up one band fixes that.
Just like the Panache sports bra - tight band and tall (huge on me) cups. I bought this at the same time as my 32G Natori Zen (which is technically too small for me now) knowing it was too big but assuming pregnancy weight gain would make it fit me at some point. At 33 weeks pregnant, this is not going to happen unless I gain another two or three cup sizes or my boobs find the space on my chest to grow taller instead of more projected.
I have no idea why I keep buying Panache Sports and clones - they're severely overrated in my opinion, and they never fit me right. If I size down to where I can fill the cups, the gore always floats. Can't win with this shape.
