I just received this bra in the mail and tried it on immediately. I ordered a 38H. I'm measuring 38" around my ribcage and 47" around my breasts. According to standard sizing I should be wearing a 38I (I was a 36H pre-pregnancy). The band on the 38H fits perfectly on the loosest clasps, and the cups are slightly large on me. I actually like this since my breast size changes slightly throughout the day. If  anything it might have ordered a cup size smaller and have been okay. The one reason I took away a star is that the bra comes up very high on my chest and I won't be able to wear this bra with tank tops or any other shirts that don't have a high neckline. Overall, its giving me great support, and I wanted an underwire nursing bra I could toss on when I am leaving the house or have guests, and with my size I couldn't find something at the few stores I've checked out (as was the case pre-pregnancy, as well). As others have noted, this bra has little padding but the material is thick. It doesn't seem like other molded bras I have owned, but its thick enough that I don't see my nipples through my shirt.
