Quick Answer
To measure for a lace bra, you'll need a soft measuring tape and a non-padded bra. Measure your band size directly under your bust, then measure the fullest part of your bust. Subtract the band measurement from the bust measurement to find your cup size. Always try on lace bras in your calculated size, as lace can stretch slightly over time.
Why Lace Bras Need a Different Measuring Approach
Lace bras, unlike seamless or padded styles, have less built-in structure and rely more on the fabric's natural stretch and the fit of the band. The lace itself can give slightly over time, so a snug band is crucial from day one. Because lace doesn't compress like foam, a properly measured band and cup ensure the lace lies flat without gaping or digging in.
Tools You'll Need
Grab a soft measuring tape (the kind used for sewing), a non-padded bra that fits reasonably well, and a mirror to check your tape placement. Avoid using a metal tape or a piece of string, as they can introduce errors. Wear the non-padded bra to keep your bust in a natural position without adding volume.
Step-by-Step Lace Bra Measuring Guide
- Measure Your Band Size: Wrap the measuring tape snugly around your ribcage, directly under your bust. Keep the tape parallel to the floor and snug—not tight. Exhale and take the measurement in inches. If the number is even, that's your band size. If it's odd, round up to the next even number. Common mistake: Measuring too loosely. A too-large band won't support the lace, causing straps to slip.
- Measure Your Bust Size: Stand straight and wrap the tape around the fullest part of your bust, keeping it level across your back. Don't pull tight—the tape should just touch your skin. Write down this number in inches. Checkpoint: Make sure the tape isn't dipping in the back or pulling across your nipples. Use a mirror to verify.
- Calculate Your Cup Size: Subtract your band measurement from your bust measurement. Each inch of difference equals one cup size: 1 inch = A, 2 inches = B, 3 inches = C, 4 inches = D, and so on. For example, a 36-inch band and a 38-inch bust gives a B cup. Common mistake: Forgetting that cup size is relative to band size—a 34C is not the same volume as a 36C.
- Try On the Bra and Adjust: Once you have your size, put on the lace bra and fasten it on the loosest hook. The band should feel snug but not painful. Lift your arms and move around—the band should stay in place. Adjust the straps so they sit comfortably without digging in. Checkpoint: If the band rides up in the back, go down a band size. If the lace cups gap or wrinkle, go down a cup size.
