Bras in Large Sizes – A Guide

Short answer: A bra without underwire in a large size needs a wide band under the bust, wide straps and a firm, stretchy fabric to give proper support. Choose the right model, and you can easily have both comfort and hold without underwire.

The support comes from the band, not from the underwire

Up to 80 percent of the support in a bra should come from the band around your body, not from the straps or the underwire. That is why a wire-free bra can work perfectly well for a larger bust, as long as the band is wide and sits firmly without squeezing. Wide straps spread the rest of the weight, so they do not cut into your shoulders.

What to look for

Choose a model with plenty of fabric in the cups, double layers of fabric and a wide back band. A bamboo bra without underwire also gives you softness and breathability, which matters even more when the bra covers more skin. Read the guide to bras without underwire as well, to understand the differences between the models.

The size has to be spot on

The bigger the cup, the more important the right size becomes. Measure yourself at home, and check the brand's own scale, for example the size guide for JBS of Denmark women, or use our general guide to finding the right size in bamboo clothing.

Frequently asked questions

Can a bra without underwire support a large bust?

Yes, if it has a wide, firm band under the bust and wide straps. It is the band that carries the weight, not the underwire.

How do I stop the straps from cutting into my shoulders?

Choose wide straps, and make sure the band sits tightly enough to carry most of the weight. If the straps cut in, they are carrying too much.

Should I choose a size up in a wire-free bra?

No, choose your normal size. The elastic has to sit snugly to support you, and a bra that is too big loses its hold.
