With a bra on, wrap a tape measure snugly, but not too tightly, around your rib cage, just below your bust line. This is your band size (US/UK sizing uses inches).
Then, wrap the tape measure around the fullest part of your bust. If the difference is:
1" / 2.5cm your cup size is A
2" / 5cm your cup size is B
3" / 7.5cm your cup size is C
4" / 10cm your cup size is D
About the Designer
Founded by artisan Ada Masotti in Bologna, Italy in 1954, La Perla gets its name from its earliest pieces—which were presented like jewels in velvet-lined cases. Taking cues from modern trends, La Perla undergarments were some of the first to make a bold impression in striking colors and patterns. In the decades since, La Perla has expanded its line from simple bras and panties to swimwear, lingerie, and shapewear. Found in fashionable boutiques across the globe, La Perla lingerie carries with it Masotti’s dedication to well-tailored underwear while creating new styles and shapes that fuse innovation with tradition.
