Experienced runner training for half marathon. Had this bra in the 34 D and outgrew it after baby. Got Fiona 34DD and is true to size.  I also got the Maia in a 34DD because it had great reviews but I don't feel as sporty in that one because of the extra material around the chest that practially goes up to my neck. The fiona bra still makes me feel sporty while being supportive. Keeping both of the braas because the quality is fantastic. I have had my others for years and continue to buy only this brand running braa. Great price through amazon as well. Both braas run true to size. Thanks for helpful reviews on amazon I could buy these online without having to go into store to fit for size.
