100D Bras

What to look out for

Sister sizes for 100D: 95E. If 100D 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.

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

Good to know

A band of 100 means a measurement of 98-102 cm under the bust. Combined with a D cup it gives a size that ends the size grid in many shops - and in practice it calls for the same rules as any other: a close band, a flat wire, a gore that sits against the chest.

With a wide band the height and firmness of the sides matter especially. Soft, low sides roll up and dig in, while higher ones with sewn-in reinforcement keep the band level. The number of hooks is just as important: four rows let you take the band in as the fabric stretches.

The sister sizes are 95E and 105C. If you are looking for a similar cup volume in another band size, check the 95D and cup D collections.

The collection is made up mainly of Selene styles, with a few additions from Sielei. Most are smooth everyday bras with a full cup, easy to wear under a shirt or jersey. Before ordering, compare the band measurements with the size chart - with a wide band a difference of two centimetres changes the whole support set-up.

If you buy lingerie online, start with one style and only order further pieces from the same series once you have checked the fit. With wide bands the differences between styles are often greater than the differences between neighbouring numbers, and repeating a cut you have tested saves time and returns.
