How to find your size
Sister sizes for 80B: 75C, 85A. If 80B 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, padded and push-up models work well because they add volume, as do smooth cups under fitted clothes.
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 60 days to return.
Size 80B pairs an underbust measurement of 78-82 cm with a difference between measurements of 13-15 cm. It is a proportion typical of a wider ribcage and a smaller bust volume, where the usual problem is not support but fabric wrinkling across the cup.
The sister sizes for 80B are 75C and 85A. With a wide ribcage, the version with a narrower band often turns out to be more comfortable, provided the fastening has three rows of hooks.
Choose your size from measurements rather than memory, and set them against our size guide. We have gathered tips on styles in our guide.
Which style to choose
If the fabric creases, reach for a moulded or lightly padded model - it holds its shape regardless of how the breast sits. If, on the other hand, the cup digs in at the side, a change of style is usually enough: a balconette has more widely set straps and a shallower top, a half cup exposes the upper part, and a full-cup model covers everything and stabilises best.
What to look out for
Pay attention to the number of hooks and to the elastic along the bottom edge. Wider elastic marks the skin less and stays springy for longer. If you wear a bra every day, keep at least two in rotation - elastic fibres need a break to return to shape.
More about this category
Colour is worth remembering too. Under a light, thin blouse, the shade that disappears best is the one closest to your skin tone, because white shows through more than beige or nude.
Frequently asked questions
How many centimetres is a band size of 80?
About 78-82 cm measured directly under the bust.
What are the sister sizes for 80B?
75C and 85A.
The fabric creases at the top of the cup - what does that mean?
Most often the cup is too big or the style has a deeper top than you need. A moulded model or a balconette helps.
How many bras is it worth keeping in rotation?
Two to three for everyday wear, so the elastic has time to return to shape between wears.
