wonderbra sizing

[mouselittle]

hi, can anyone advise me on wonderbras.

I have put my measurements into their online bra size calculator and came out as a 38AA

considering I'm wearing a m&s 32DD at the moment (which just fits - badly-) and was falling out everywhere from various 34B and 34/36C bras, I find this hard to believe.
I tried on a 32F wonderbra the other day and it was a bit big but not excessively so.
do they generally run true to size or bigger/smaller?
I want to try ordering online but I don't think 38AA will fit so where should I start?
my measurements are 31 under bust, 36/37 over.

Please ignore on-line calculators, with a few exceptions they are all wrong.

I'd try a 30E/F and a 32DD/E (although it sounds like a 32FF isn't working for you so inspect 30 is the way to go).

In the Wonderbra Ultimate Strapless, you'll need a 32 band.

success! have bought 30e in their t shirt bra.

Excellent news!
