Bras cup E
A cup E means a difference of about 20 centimetres between the bust circumference and the underbust circumference. In British sizing, this usually corresponds to DD. In practice, the letter describes the difference in circumferences, not the absolute size of the breasts: the same cup size with an underbust of 70 and 90 means a completely different volume.
From this size upwards, support depends mainly on the band, not on the straps. Choose models with full cups, a high side under the armpit, and wide straps. Push-ups usually interfere because they add volume to the top of the breasts.
Check the size with two measurements: measure the underbust tightly, on exhalation, and the bust loosely, at its widest point. The difference indicates the letter, the underbust circumference - the number. Each size has corresponding sister sizes: the same bust will also fit in a band one size smaller with a higher letter and in a band one size larger with a lower letter. If your size is temporarily unavailable in a particular model, this is the first place to check.
The band under the bust should lie horizontally and be able to be pulled out by two fingers, the underwire should lie on the ribs, not on the breast, and the straps should not leave marks.
