So, I normally wear a 34 DDD (F) and now that I'm pregnant, I'm somewhere between an F & G.  This bra definitely holds you in, but in my opinion runs small.  Now, after the baby and as I start working out, this might not be bad at all because the tight will help keep the bounce down.  But right now, it is way smaller than a glamorise 34 F/G (wrap front) bra that I also bought.  I might order another one to finish out the last couple months of my pregnancy, but I think I'll go 36 for sure.
