I wear a 42DD, and i measured right under my boobs and above to get that sizing. So 42 under the boobs and 47 above the boobs. Well, I am happy with this bra. I mainly wear t shirts but I still love having support when i go out, so I was skeptical since i trust the wire bra more but this one worked out so well! I felt supported, it has a double band along the bottom that really supports you. Then the material wasn't really bulky for me since i wear t shirts and it didn't feel bulky wearing it. The cup decorative pattern feels light and non bulky. I also was so happy with the bands. Sometimes you buy a bra and you make the bands the shortest they can be and your boobs still don't feel supported, well this bra lets you lift the girls up! And it feels supported and the adjustable bands feel sturdy and are kinda thick too but it didn't hurt wearing this bra and i wore it for 7 hours. I am also so happy with the side boob bra coverage. it's a whole 6 inches of side coverage! I recommend this for the price, it's cute and i'd say it's good as a t shirt bra, but probably not to wear underneath and thin blouses or thin women's shirts
