Step 1: Measure the four data
tools with just one soft tape, close to the body or naked, and stand naturally:
1. Upper bust: Lean your body forward about 45°, with the tape circling the highest point of the nipple horizontally. Leaning forward allows the chest to naturally align properly; standing upright results in a smaller measured amount.
2. Lower bust: The soft tape measure should be placed tightly against the lower edge of the breast, wrapped around the back, and kept level; Take the state at the end of exhalation and before inhalation; don't hold your breath.
3. Waist: Find the thinnest part of the body (usually 2–3cm above the navel), use a soft tape to fit naturally, and the tightness should fit enough for one finger. Don't tuck in your abs; the number after tucking in is not your true waist circumference.
4. Hips: Stand straight with your feet together, and a soft tape circle horizontally around the fullest part of your hips.
Three details determine accuracy: the soft ruler should always be parallel to the ground, close to the body but not dented into the skin, and the same area should be measured twice and averaged to the same area.
Step 2: Calculate cup size, fixed
size cup size = upper chest circumference − lower bust
difference cup size approximately 10cm
A
Approx. 12.5cm
B
Approx. 15cm
C
Approx. 17.5cm
D
For 20cm and above
, E and
above, the lower bust is used to determine the base circumference: 68–72cm picks 70, 73–77cm picks 75, 78–82cm picks 80, 83–87cm picks 85.

(unit: cm). This table is based on elastic fabrics; For non-stretch lace and leather styles, please align according to actual measurements; don't pick too many options. Step
4: Three rules for determining whether to go larger or smaller
- Elastic mesh yarn/spandex: has a large elastic allowance, so select according to the lower limit; If you want a close, wrapping feel, choose a size smaller.
- Non-stretch lace/leather/strap version: No stretch space, must strictly align with actual data on the table, preferably one size larger.
- Bodysuits and nightdresses: In addition to measurements, height and weight also matter. If the length is too short, it will claw and feel restricted.
- Bust size between two sizes: prioritize size by bra—the bust is the part of the lingerie that tightens the most.
On theproduct detail page, Miqu lists the elasticity of each fabric and the actual flat size to address the industry issue of "same size but different versions"; Before placing an order, compare your data with the flat size; the return or exchange rate will noticeably decrease.
16-character mnemonic
:Measure up, measure down, calculate the cup's circumference; Small but not large, chest priority first.
