How to measure your bra size at home: what you need to know
To learn how to measure your bra size properly, you’ll need to know the basics. To begin with, know that bra measurement are calculated based on your band size (number) and cup (letter).
But then how do you know exactly your band and cup size? This is usually determined by measuring around your rib cage, right below your breasts, and your bust at the fullest part of your chest. Knowing your breast shape also plays a huge factor in your size and what type of bra will be the perfect fit for you.
Also, try to not round to a whole number when you are looking at these measurements. For in-betweeners, you can opt for bras in half-cup sizes if you don’t want to settle for even half an inch of discomfort.
As there’s no actual one-size-fits-all bra (even if you’ve learned how to measure your bra size properly!), you’ve also got to know your sister size or bra size equivalent. Sister sizing is when you have the same cup volume and different band size.
For example, if you find that a 34C fits great in the cups, but the band is too tight, you’d need to adjust both your band and cup size to a 36B.
Tips in choosing the right bra size
Before getting down to how to measure your bra size, first, you have to learn some tips in choosing the perfect fit. Identifying your breast size is important as everyone has a different breast shape: yours can be asymmetric, athletic, bell, east-west, relaxed, round, side set, slender, or teardrop-shaped.
Identifying common problems, like gaping cups and slipping straps, can determine which size bra you should actually be wearing and whether you need to go up or down a size (or half-cup size). And last but not least, note that different types of bras fit women differently, and are more suited for your lifestyle, so make sure to always find your favorite cup type.
