When you have a F 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. 40F 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.
If you want to feel supported throughout the entire day (and look good while your bra is doing all the hard work), opt for size 40F full figure bras. Women with larger cups choose our 24/7® Perfect Coverage Bra as their ultimate everyday style due to its sleek design and smoothing sides that create a stunning silhouette. With thin memory foam cups and adjustable straps, this 40F bra is the very definition of comfort and support. If you’re looking to reduce your chest size up to 2 inches to look neat and stylish in button-ups and other specific clothes, try our 24/7® Unlined Minimizer Bra. It provides amazing support along with style and a boost of confidence to wear whatever you like no matter your bra size. If you’re looking for wireless 40F bras, our Sculpting Wireless Minimizer Bra will support you in the most comfortable way, seamlessly disappearing under any outfit. Our 24/7® Second Skin Unlined Bra is so light and smooth you’ll forget you’re wearing a bra at all!
A 40F bra should fit you like a glove without feeling too tight or too loose. Make sure your breasts fill out the cups without spilling - that’s your number one red flag when it comes to size 40F bras. The band should sit just beneath your breast and hug the torso, supporting you in a comfortable way. The straps of your bra should stay up no matter what.
Finding your perfect bra size can be difficult. That's why we created our Online Fitting Room Quiz! No need to give in to bad bras or confuse yourself with sister sizes. Take our quick quiz to find the band and cup size that will best fit your body in minutes.
