I've seen a couple sites list
144cm ~57" as her overbust. Haven't found a consistent cup size, but the largest size I've seen listed for her is LL=M=13" cup... That would make her a 44LL, but that's not official, obviously. Assuming that the 57" measurement is correct she measures a 38T/S, 40R/Q, 42P/O, 44N/M, 46L/K, 48J/I etc... That's body measurement, though; she may wear a bra that doesn't 'add up' w.r.t. the official sizing chart. If recent surveys are to be believed, over 80% of women wear the 'wrong' size bra for various reasons...
