I ordered this bra in a size 40 F, b/c that is what I had been wearing in my Motherhood Maternity Bra.  It was WAY too small, so I went to a boutique and got sized, they said I was an H/I, even though the F I had from Motherhood Fit.  SO, I ordered a size G, b/c there was not H in a 40.  It is still too small, but it is doable, I did not want to do another return, I was desperate for a bra.  If I could have gotten it in an H, it would be perfect.  I love the material and the support.  Also, amazon was great about returning, it was simple.
