UPDATE!!
UNDIEEES!!
unfortunately my nana bought me all these but none of them fit me, she seems to think a 'D' is close enough to a 'C'. unfortunately not.
so, without further ado, i present:
blue bra & gstring- au10C (US 32C) never worn
minty green bra, au10C, never worn
baby pink bra & underwear set, 12C never worn
