SIZE GUIDE
The best shape and support is achieved by a cup that covers about 75% of your breast area. If cups are too big for you, they will swamp your breast area and you’ll end up with pancakes instead of lifted rounded breasts!
There are 2 ways to find the right InvisiBra size for you. The quick route is to convert your UK bra size into InvisiBra size. The more accurate route is to measure yourself according to our measuring guide. Because InvisiBra is a backless bra, our sizes come in cup sizes only (A, B, C, D), without the band size (30, 32, 34) element.
