The larger one, then you can pad the smaller one.

I don’t sew bras but I know a thing or two about fitting. Measuring for the overbust makes no sense if you buying a bra off the rack.

Good gravy - I just did this fitting and found that I’m the same size - 32G! I didn’t know that was a choice! Checking out ASOS ASAP. It is really hard to find bras when you just are just big busted, not all-over large. I have been wearing 34C for a long time and tried going up to 36D recently, and it still isn’t…

I’ve only gotten poor and poorer “fittings” from live human beings of various venues, across multiple states.
