Bra Cup
When you have a C 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. 42C 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.
Starting with our crown jewel, the classic T-shirt bra. It is an ultimate everyday timeless masterpiece that offers a silky smooth look under your garments.
If you are looking for a 42C push-up bra, our Classic Uplift Plunge Bra is our take on the push-up bra. For the days you want extra oomph and cleavage, this bra will suit the occasion. It gives you a natural lift for a beautiful silhouette.
Cotton lovers, rejoice! Our organic cotton bra has you covered. Its gentle fabric will leave you feeling extra cozy and relaxed in your cotton 42C bra.
The key to a perfect fit for your size 42 C bras is ensuring they feel snug but not tight. If the bra has an underwire, it should sit comfortably against your chest. The band should be snug but not too tight. The straps should be to the preferred length without slipping or digging in.
Your ideal 42C bra is stylish and comfortable, and at ThirdLove, we’ve got just the thing for you, whether you’re looking for smoothing support or lifting shape enhancement.
