I realize this is an industry wide complaint, but getting bra sizes right is part of your business plan. Band sizes are out of this world crazy! Several brands use the old sizing method: measure the rib cage and add 2" for the hook rows.
You Tomasina's hints is sometimes helpful, but not always. Would it be possible to get sizing info from each of the manufacturers you carry?
Hello Joan - Looking at your last order with us, the issue looks to be that you have purchased the same size in 2 bras, but one is a US size and the other is a UK size which means your cup sizes are 2 sizes different. We have reached out to you to better assist you with sizing.
Kind Regards,
Wilma
