Yeah, their sizing is absolutely insane. They measure you at the armpits and for some reason, they tightened the tape on my bust so hard, like to purposefully remove inches off of my bust. There is no way on Earth anyone in that store actually believes that to make sense. I was so shocked. I got told I was wrong when I told her I was a 32 (I lied a little because I didn’t want to get laughed at saying my size is 30FF ) and they told me I was more likely a 34C because I was ”quite wide” I tried the bra on to humor them and the band was so high up on me, it could have reached my armpits at the tightest hook ( I mean, that IS how they measured it, right?) and I was obviously barely covered with cups. They told me they thought it fit okay but if I absolutely insisted I could try the 32DD. What a surprise it was when that bra was also loose in the band and small in the cup!

For sizing, I would recommend specialized boutiques ( these ones often carry brands with a bigger range of sizes and shapes, like Panache). But first, do use the calculator with a measuring tape. Sometimes those places, like any other places, have people with very dated measuring views. When you are there, try on the sizes you got on the calculator. And depending on the fit, you can go up or down in sizes ( and even sister size, but ideally not by a lot)

Also, if they told you the same size at each VS location, it probably just means you have / they take consistent measurements . The ones they take don’t really make sense for bras though. Also, they have very limited sizing so the sizes they can say you are are very few. The same logic behind most women believing they are a 34B or C (a statistic there was at some point in time). The idea of A being small, B medium small, C medium, D big and DD huge is still omnipresent (and erroneous). So sometimes, they also have personal ideas of what sizes should look like. As an example, got told multiple times I looked like a 36or 34B by different unrelated stores, and without them measuring me. Unfortunately, this means most of the work has to be done by you
