Lolita Sizing: How to Read a Chinese Measurement Chart
Almost every fitting problem with an indie Chinese piece comes from the same mistake: treating the size letter as the answer. Ateliers size by measurement, and the same "M" from two makers can differ by several centimetres. The chart is the specification; the letter is a label.
Measure yourself first, in centimetres
You need four numbers for most Lolita garments: bust at the fullest point, waist at the narrowest, hip at the fullest, and shoulder across the back from joint to joint. For a full-length OP or a skirt, add the length you want from waist to hem. Measure over the underwear you would actually wear with the piece, keep the tape level, and do not pull it tight. Write the numbers down in centimetres. Converting from inches at every step is where errors accumulate.
Read the chart, not the size letter
A chart usually gives either a fixed measurement or a range. A range means the garment stretches or adjusts to it, and the top of that range is a maximum, not a comfortable fit. Sitting at the very top of a bust range in a boned bodice will not be wearable for an afternoon. "Free size" or "one size" means one fixed set of measurements, so check it like any other size. Where a piece is fitted or structured, aim a little below the maximum rather than at it.
Shirring, boning and lacing change the answer
Construction decides how much the number can move. Back shirring adds real give and widens the workable bust range. Lace-up panels let you take a bodice in or let it out by a few centimetres. Boning does the opposite: it holds a fixed circumference and will not yield, so a boned corset or bustier has to fit at its stated measurement. A petticoat changes nothing about fit but does change hem length, because volume lifts the front hem, allow for that when you pick a skirt length.
When your measurements disagree with each other
Almost nobody matches one size across all four numbers, so the question is which measurement decides. For a JSK or an OP it is the bust, because a fitted bodice cannot be let out and everything below it has more tolerance. For a skirt it is the waist, full stop. For a blouse it is the shoulder. A bust that is slightly tight reads as fitted, but shoulders that are too narrow pull across the back and cannot be fixed. Where the deciding measurement is at the top of its range and another is comfortably inside it, size up on the deciding one and accept the looser fit elsewhere; the reverse almost never works.
The chart vocabulary, in the original
Charts are usually written in Chinese and the terms are consistent between ateliers. 胸围 is bust, 腰围 waist, 臀围 hip, 肩宽 shoulder width, 衣长 garment length from the shoulder down, 裙长 skirt length from the waist. 均码 or 均一码 means one size. 可调节 means adjustable, and 后背松紧 means the back is elasticated, both signal give. A number written as a range (86-96) is what the piece adjusts across; a single number is a fixed measurement. Units are centimetres unless the chart says otherwise, and a chart mixing 尺 or 寸 with centimetres is worth querying before ordering.
Checking the piece against the chart on arrival
Measure a garment flat, not on the body: lay it out unfastened, measure across the bust seam and double it, and compare against the listed number. A few centimetres of variance is normal on handmade and small-batch pieces, and it is not the same thing as a defect. What is worth raising is a measurement well outside the stated range, an asymmetry between left and right, or a fastening that does not close at the size it was sold as. Our pre-shipment inspection covers construction and measurement against the listing, which is the point at which a mismatch is still cheap to resolve.
