Standard sizing assumes a woman who does not exist. What asymmetry, root width, tissue density and the monthly cycle really do to fit — and how a house builds for them.
Ready-to-wear lingerie is built on an assumption so convenient that the industry has stopped noticing it is an assumption: that a woman is symmetrical, that her shape is stable across a month, and that a single number and a single letter describe her. None of the three is true of anyone. The gap between that fiction and the woman standing in front of the mirror is the entire reason a fitting room exists.
Volume is not the same as position
A cup size describes a difference between two measurements. It says nothing about where that volume sits, how far it projects forward, how wide it spreads across the chest, or how much of it is above the apex versus below. Two women who both measure the same difference may need cups whose seam placement differs by a centimetre and a half — a distance that decides whether a garment fits beautifully or gapes at the top edge all day. This is why measuring correctly and fitting correctly are two separate skills, and only the second one produces a good garment.
The vocabulary a fitter uses is about placement, not size. Root width — how far across the ribcage the breast tissue is attached — determines wire choice before anything else. Root height decides how tall the cradle must be. Fullness distribution decides where the vertical cup seam falls. Tissue density decides how much the shape will move when the woman moves, and therefore how firm the lower cup must be. None of these appear on a size label.
Asymmetry is the rule
Almost every woman is asymmetrical, and a meaningful proportion is asymmetrical by a full cup or more. The industry's answer is to pretend otherwise and let her sort it out with a strap adjuster. Ours is simpler: fit the larger side and build the smaller side with more give — a slightly softer upper cup, a marginally longer strap, occasionally a different panel entirely. A woman should not have to choose which half of her body the garment is for.
“We do not correct the body to suit the pattern. We correct the pattern, every time, and we do not tell her it was difficult.”
The fitting room, Bangkok
The month, and the year
Breast volume commonly varies across a cycle, and ribcage measurement varies with it. A garment fitted on one day of the month can be genuinely uncomfortable on another. This is not a defect to be solved by buying a larger size; it is a design problem, and the design answer is to build tolerance into the right places. A stretch-lace upper cup absorbs volume change without losing the shape below it. A band with a well-chosen elastic and a range of hook positions absorbs ribcage change. Rigidity where the garment must hold, elasticity where the body must be allowed to move — that is the whole grammar.
- Root width sets the wire. Nothing else does, and a wire that is too narrow will sit on tissue and hurt within an hour.
- A gaping upper edge means the volume is right but the depth is placed too high — a seam correction, not a size change.
- A band that rides up means the band is too loose, regardless of what the tape measure said.
- Straps that dig are almost always a symptom of a band that has stopped working, not of straps that are too thin.
- Spillage at the underarm calls for a taller wing, not a bigger cup.
Bodies that have carried and fed
Pregnancy, feeding and the years after them change ribcage circumference, tissue density and root position, sometimes permanently and rarely symmetrically. A woman who was fitted well at twenty-five and badly at thirty-eight has usually not changed size; she has changed shape, and the pattern that suited the first shape is simply describing a body she no longer has. The remedy is a new fitting, not a larger label, and it takes about forty minutes.
What we do differently on the table
We work from a block, not from a size chart. The block is a proven starting shape; the fitting is where it is argued with. We pin the cradle first, because the frame decides everything above it, then set the wire, then adjust the cup seams, then — last, always last — the straps. Fitters who begin at the strap are treating the symptom. In a made-to-measure piece we will move a cup seam by six millimetres if the mirror asks for it, and we will do it without discussion, because the point of the exercise is a woman who forgets she is wearing the garment.
Why this is worth the trouble
A well-fitted piece of lingerie is the only garment that changes how every other garment sits. It sets the line of a dress, the fall of a silk blouse, the whole vertical proportion of a body in a mirror. Women describe the effect as looking slimmer or taller, and what they are actually describing is a garment that has stopped fighting them. That is not a cosmetic achievement. It is an hour of somebody's attention, converted into a decade of not thinking about it.
