When you have a D cup, you want to be supported and comfortable in your bra. But a lot of bras suck. Here at ThirdLove, we make better bras for women of all cup sizes, including full and half cups (if you're between sizes). It's important to wear a bra that fits you perfectly with the extra support you need, especially with a larger bust. 40D bras at ThirdLove are designed to fit your body. They will hug and smooth your curves the way you like so you look and feel great every day.
