Bras 80D

We have 111 models in this size: 80 is the underbust circumference in centimeters, and the letter D indicates the cup size, which is the difference between the bust circumference and the underbust circumference.

Sister sizes for 80D: 75E, 85C. If 80D fits well around the band but the cup digs in or gapes, opt for a sister size instead of just changing the letter – the cup volume will remain similar, but the band size will change.

With this cup size, support is key: underwires, wider sides, and a multi-row clasp support the bust without straining the shoulders.

Remember that brand sizing varies – for each product, we provide the manufacturer's size chart. We have described how to measure on the How to choose your size page. Shipping via Paczkomat is PLN 12.99, free for orders over PLN 199, and you have 14 days for returns.

How to find your size

Sister sizes for 80D: 75E, 85C. If 80D holds well around the band but the cup digs in or gapes, reach for a sister size instead of changing only the letter — cup volume stays similar while the band changes.

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

Remember that size grids differ between brands — we publish the manufacturer's chart with every product. We have explained how to measure on our How to find your size page. Parcel locker delivery is PLN 12.99, free from PLN 199, and you have 14 days to return.

At 80D the underbust measurement is 78-82 cm and the difference between measurements is 19-21 cm. It is a size where differences between manufacturers' size grids are clearly visible - the same number from two brands can give a different cup depth.

Before ordering, compare the measurements with our size guide, and if you are looking for matching bottoms, see our microfibre knickers, which do not show under jersey.

What to look out for

So rather than sticking to a single marking, look at the result once it is on. The cup is right when the breast fills it with no empty space and without spilling out at the side or the top. The band is right when, fastened on the middle row, you can slide two fingers underneath and no more.

The sister equivalents are 75E and 85C. If the fastening feels tight but the cup sits correctly, that swap is the first step.

Which style to choose

In this bracket, models with a higher side panel, detachable straps and a seamed cup work well, because they hold their shape better than a one-piece cup. For backless dresses, a band extender or a bandeau-style model comes in handy, though at a fuller volume it gives less support.

If you are buying several pieces at once, pick one smooth model for fitted clothes and one lace model for the evening. This simple pairing covers most situations and lets you keep up the rotation that keeps the elastic holding for longer.

Frequently asked questions

What are the sister sizes for 80D?

75E and 85C.

How do I check that the band is not too loose?

Fastened on the middle row, it should pull away from your back by no more than the width of two fingers.

Do sizes differ between brands?

Yes. The same number from different manufacturers can have a different cup depth and a different underwire length, which is why it is worth reading the description of the specific model.

What should I do if my breast spills out under the arm?

Reach for a model with a higher side panel and a deeper cup - that kind of construction gathers the tissue from the side.
