The 34G is on the tighter side but still fits and I'm sure it will stretch a bit over time. The cup size is perfect. Great support in the cup area and my mom noticed right away that my posture looked good and I've had friends ask me if I've lost weight. I finally have a bra that flatters me. My advice is make sure you order the right size for you. Your breasts change over time and department store sizing only goes to D usually so they measure you to what they can sell you. I checked my size online on Thirdlove.com but I never order their bras because I can't pay those prices. Check your bra size there then come to Amazon and order your bras that fit! I have heavy breasts and this provides the lift I need and full coverage. No added padding or bulk. I'm in my 30s and this bra makes me feel like my breasts are also in their 30s and we'll supported!
