75D bras

We have 108 models in this size: 75 refers to the underbust measurement in centimeters, and the letter D indicates the cup size, which is the difference between the bust and underbust measurements.

Sister sizes for 75D: 70E, 80C. If the 75D 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: underwire, wider sides, and a multi-row clasp hold the bust without straining the shoulders.

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

What to look out for

Sister sizes for 75D: 70E, 80C. If 75D 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.

More about this category

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

Good to know

In size 75D the underbust measurement falls in the 73-77 cm range and the difference between measurements is 19-21 cm. A narrow band with a substantial cup volume means the construction has to be well thought through: what counts is the width of the centre gore, the length of the underwire and the height of the side panel.

The underwire should encircle the breast tissue across its full width and stop in the hollow under the arm. If it rides onto the breast from the side, the model is too small in the cup, not too big in the band. The centre gore, the part between the cups, sits flat against your chest when the fit is right - when it lifts away, you need a bigger cup.

The sister equivalents are 70E and 80C. They are worth checking when the band itself feels wrong, because the cup volume stays similar.

At this volume, models with a divided cup and a horizontal or diagonal seam work more comfortably - they lift and spread the weight better than a single moulded cup. Straps are best chosen wider and set closer to the centre of the back, as they slip off less often. If you want comfort after a workout, see our sports bras.

Compare your measurements with our size guide before placing an order.

When buying online, check as well whether the model has detachable straps and whether they can be crossed over - that is a simple way to wear the same bra under a top with a low back without investing in a second one.
