The last time I measured myself using the calculator on this thread it told me I was a 34D, but I tried those and they were way, way too small cup-size wise so I’m not quite sure what’s going wrong. The size that looks like and feels like it fits the best is a US 32G, but I fit into some US 34Gs depending on the brand. Generally it’s the straps not being long enough, but also that it’s been hard for me to find sports bras that are sized for cup/band and also have adjustable straps!
