I had no problems with the sizing. I have had this bra for almost a year now and I only wear it in bed. It is ok but what drives me crazy is that the elastic band under the bust gets twisted up. It is one inch or so wide and is in this fabric tunnel where it twists, folds etc. You can straighten it out but that it will undo itself soon afterwards. The fabric started pilling almost immediately because of the synthetic but that I can live with that. I prefer to wear my pre-pregnancy no-underwire sport bras or bras with spagetti straps instead. They give at least the same amount of support and are more comfortable.
