I measured myself as per the bra guru instructions and came up at something like a 36G/GG (in a 38FF), I bought a few different bras in the new size and they were all terrible. The bands were unbearably tight and the cups were huge! I scooped and scooped until I could scoop no more and they were still ridiculously too big and baggy. I changed them all for 38FF and they were perfect.
Has bra intervention not worked for anyone else or is it just me?
