Help needed with translating la senza 8,10,12d/dd sizes

Hi!Sorry to bother You with this but I want to buy some lingerie from La Senza online and I can't get the info I need from customer support!I got a quick reply to call my nearest store but they don't carry D+ babydolls so it's a dead end.
My "always fits" bra size is 34C but sometimes the underband can be too wide.My measurements fall between sizes (73cm/ 90-91cm) so I have a lot of 32D's and 32DDs that fit just as well.
Does anyone know what size La senza D/DD babydoll(they come as 8 D/DD, 10D/DD etc) translates to bra size size 34C (or 32D/DD). I'd appreciate it a lot!Thanks

I found this bra size converter online. Maybe the babydoll comes in Australian sizing. Which La Senza site are you looking at?
