>>79976501Not necessarily - it depends entirely on the store! I've been incorrectly sized before. As a rule of thumb, the gore should rest comfortably against you instead of gapping or digging in, the band should feel secure but not leave red indentations after short periods of wear, and there should be little (but preferably none, dependant on cut) spillage from any side of the cup. The most reliable way is to measure yourself with a fabric tape measure. Remember, different countries have different bra sizing too, so make sure if you're using a guide to make sure it's from your country or accounts for it.
I saw your other reply saying that you got measured at VS - sorry, but it's very likely wrong in that case... Try the ABTF calculator that another anon linked!
>>79976572It is, isn't it? Clothing sizing in general is fascinating, especially how it differs between countries! My first wish is that Doppio gets all of the love in the world, but my second is that everyone wears clothes that fit them comfortably and make them feel nice...
