The E cup represents a fuller bust volume, sitting several sizes up from standard high street offerings. Whether you're wearing a 28E for a petite frame or a 48E for generous proportions, understanding your E-cup measurements ensures you find bras that deliver proper support, comfort and all-day wearability. E-cup sizing suits women with naturally fuller busts who've struggled finding adequate coverage in limited retail ranges. We stock E-cup bras across all band widths, so you can find your perfect fit regardless of your frame size
