Bra Fitting

Finding Size by Trying On

Bra fitting is the process of finding the correct size and style for an individual wearer, and its central principle is that trying garments on is decisive. Although there are established methods for measuring for a bra, the only real way to fit a bra is by trying them on, and finding the correct size by trial and error. Measurement is a useful starting point because it narrows the range of sizes to try, but sizes vary between styles and brands, and the shape of a cup, the stretch of a band and the placement of underwires all change how a given size actually fits. Many people have difficulty finding a bra to fit, and this must in part be due to a lack of understanding of how a bra works, as well as flaws in the standard measurement system. A fitting therefore works through sizes and styles systematically, checking the same fit points on each garment, rather than treating a single measured size as final.

Understanding how support works is the first fit point to check. It is a common misconception that the shoulder straps should bear the weight; in fact the strap around the body, the band, should provide most of the support. The band should be firm but comfortable, snug enough to stay in place and carry the load, without being so tight that it causes discomfort. When viewed from the side, the strap that runs around the body should be horizontal and should not ride up at the back at all. A band that rides up indicates that it is too loose or the wrong size, because a correctly fitted band anchors level around the rib cage. Shoulder straps then serve mainly to hold the cups in position and shape the top of the garment, adjusted so they sit comfortably without digging in or slipping off, while the band does the main structural work underneath.

Checking Underwires and Cups

The underwires at the front provide the second set of checks. The underwires should lie flat against the rib cage, following the natural shape closely, and should not dig in, rub or poke out at the front. An underwire that lifts away from the body, presses into soft tissue, or pokes at the centre or under the arm is a sign that the cup size, the wire shape or the style does not match the wearer, and a different size or style should be tried. Wires are meant to enclose and support by their position, not by pressure at a single point, so comfort at the wire line is a practical test of whether the garment's structure suits the body it is fitted to. Checking the wires with the wearer standing naturally, moving the arms and bending, gives a more reliable result than a single static glance, because a fitting must work in ordinary movement.

The cups provide the final checks. The cups should enclose fully and there should be a smooth line where the fabric at the top of the cup ends and meets the bust. There should not be a ridge or bulging over the top or sides of the cups, even with a balconette style or lower cut shape, where the lower neckline makes the top edge especially visible. Bulging indicates that the cup is too small or the wrong shape for the wearer, while gaping or wrinkling in the cup indicates the opposite problem. A smooth cup line, a level band, flat underwires and comfortable shoulder straps, checked together on the garment being tried, are the complete set of signs that a fitting has succeeded. Because styles differ, a wearer may need a different size in a different style, and recording the size and style that passed all of these checks is the practical outcome of a good fitting session.
