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
Former TV producer and self-proclaimed "late bloomer" Emily Lau launched The Little Bra Company in 2007 after years of struggling to find the right bra for her petite frame. Wanting to save others from a similar fate, she worked with experts to design a scaled-down bra that makes the most of a smaller figure by creating a natural curve with body-contoured padding. Specializing in hard-to-find band and cup sizes, The Little Bra Company offers bras with feminine detailing and a bit of lift for figure-proportionate cleavage and a comfortable fit.
