70D Bras

Which style to choose

Sister sizes for 70D: 65E, 75C. If 70D fits well around the band but the cup digs in or gapes, reach for a sister size instead of changing only the letter — the cup volume stays similar and it is the band that changes.

What to look out for

With this cup size support matters most: underwires, wider side panels and a multi-row hook fastening hold the bust without loading the shoulders.

Delivery and returns

Washing and care

At 70D the cup is already pronounced while the band is still narrow - the combination in which fitting mistakes happen most often. All of the supporting work is done by the band, so it has to sit horizontally and fit closely, while the straps are there to position the bust, not to carry it.

The difference between the bust and the underbust measurement here is around 20-22 cm. A seamed cup, sewn from two or three panels, shapes the breast more fully than a one-piece moulded cup and is less likely to cause spillage at the top. A good fit test is raising your arms: if the bra moves up with them, the band is too loose.

The sister sizes are 65E and 75C. They are worth keeping in mind, because one brand's cut can land you a level away - with us it is easy to compare in the 75C and cup D collections.

The line-up includes styles from Lormar, Selene and Kleo - from smooth, seamless models to lace with a soft cup. If you are unsure about the number, start with our bra sizes guide and only then choose a style.

When buying online, read the description of the cup lining. A cotton-lined version is nicer for all-day wear, and smooth microfibre is less visible under thin fabric. It is a detail that does not change the size, but it clearly affects comfort.
