26DD

26DD is a bra size used in many US and international lingerie brands, combining a band size of 26 inches with a cup size labeled DD. The size reflects two measurements: the circumference around the torso just beneath the breasts (the band) and the volume of the cup that fits over the breasts (the bust). A 26DD indicates a relatively small band with a larger-than-average cup for that band.

Measuring for bra size involves two numbers: underbust and bust. The underbust measurement helps determine the band size, while the difference between the bust and underbust measurements determines the cup size. In US sizing, a difference of about five inches is commonly associated with a DD cup. Brand labeling can vary, however; some brands use E instead of DD, and UK sizing may label the same volume differently. Therefore, measurements are a starting point, with fit guided by trying on different brands and styles.

Availability and variations: bras with a 26-band are less common than mid-range bands and are often found through specialty retailers or online shops. If 26DD is not available, many brands offer sister sizes—adjusting the band size while changing the cup letter—to achieve a similar overall volume, though exact fit can vary by cut and construction.

Fitting considerations: the band should sit level and snug around the ribcage, not ride up the back; the center gore should lie flat against the sternum; the cups should fully enclose the breasts without excessive spillage; straps should provide support without digging in. Since sizing and fit can vary by brand, trying multiple brands and styles is often necessary for a comfortable 26DD.
