Getting your bra size right is the single most important step before buying online, and thankfully, measuring at home only takes a few minutes with a soft measuring tape.
Step 1: Measure Band Size
Wrap the tape snugly around your ribcage, directly under your bust, keeping it level all the way around. Round to the nearest whole number — this is your band size.
Step 2: Measure Bust Size
Wrap the tape around the fullest part of your chest, without pulling too tight, and note the measurement in inches.
Step 3: Calculate Cup Size
Subtract your band measurement from your bust measurement. The difference typically corresponds to your cup size — for example, a 1-inch difference is usually an A cup, 2 inches a B cup, and so on.
Common Measuring Mistakes to Avoid
Measuring over thick clothing, pulling the tape too tight, or measuring while slouching can all throw off your results. Stand straight and measure directly over light clothing or bare skin for accuracy.
What to Do If You're Between Sizes
If your measurements fall between two sizes, sizing up is usually more comfortable for daily wear, while sizing down can offer a slightly firmer, more supportive fit for occasion wear.
Frequently Asked Questions
Do I need any special tools to measure my bra size?
No, all you need is a soft measuring tape — the kind used for sewing works perfectly.
How often should I re-measure my bra size?
It's a good idea to re-measure once a year, or after any significant weight change, since band and cup size can shift over time.
What if my measurement doesn't match any standard size chart?
Compare your measurements to a few different charts, since sizing can vary slightly between sellers — when in doubt, contact customer support for guidance.
Can I exchange a bra if I measured wrong?
Yes, most trusted sellers, including SheStore, offer an easy exchange policy so getting the perfect fit is never a one-shot decision.
