Plus Size Maternity Lingerie

Your bust can change more during pregnancy and breastfeeding than at almost any other time, and a well-fitted bra makes those months far more comfortable. Our plus size maternity and nursing bras are cup-sized for a fuller bust, right up to a KK cup, so a big bust is properly supported rather than squashed into a stretchy one-size shape. You will find maternity bras for everyday wear through the bump, and nursing bras with easy drop-down clips for feeding, in both wire-free and gentle flexi-wire styles. Whether you are after a maternity bra for a big bust or a nursing bra for large breasts, these are made to fit and move with you.

Why Fit Matters More Right Now

Pregnancy changes your shape in two ways that a standard bra cannot follow. Your ribcage expands, so your band size grows, and your cups increase as your bust develops, then change again when your milk comes in. A bra sized only small, medium or large has no way to track both at once, which is why so many women find their usual maternity range stops fitting partway through.

Cup sizing solves that, and it matters even more for a fuller bust. Because our range is fitted by band and cup right up to a KK, a larger bust gets genuine lift and support at every stage rather than being flattened or left unsupported. That is the difference between a bra you tolerate and one you forget you are wearing.

Nursing Bra Styles for a Fuller Bust

The practical feature that sets a nursing bra apart is the clip: a drop-down cup that opens one-handed for feeding without taking the whole bra off. Beyond that, the choice comes down to support. Wire-free styles are soft and forgiving, which many women prefer in the early weeks and overnight. Flexi-wire styles use a softer, more flexible wire that gives a bigger bust extra lift and shape while still moving with your body's changes, so you do not have to give up support to stay comfortable.

Across the range you will find the labels that specialise in fuller bust maternity and nursing, including Elomi, Panache, Goddess, Hotmilk, Cake Maternity and Triumph. If you want to compare more soft and wire-free options, or see the wider maternity range, both are easy to browse alongside this collection.

Getting Fitted Through Pregnancy

Because your size shifts more than once, it helps to be refitted along the way. Many women get measured in the second trimester, when the bump and bust have settled into a new shape, and again in the final weeks before baby arrives. A good fit at each point keeps you comfortable and means you are not buying bras you will outgrow in a fortnight. Our fitters do this every day, in store or over Zoom, and you can start with our how to measure guide if you would like to check yourself at home first.

Frequently Asked Questions

When should I get fitted for a maternity or nursing bra? Many women get fitted in the second trimester, once the bust and ribcage have changed shape, and again in the last few weeks of pregnancy to prepare for feeding. Because your size can keep shifting, a refit or two through pregnancy is normal and worthwhile.

What sizes do your nursing bras come in for a bigger bust? The range is fully cup-sized for a fuller bust, up to a KK cup, with bands starting from the smaller sizes and going up. This means a big bust is supported properly rather than squeezed into a generic large.

Are wire-free or flexi-wire nursing bras better for a large bust? Both work well, and it comes down to preference. Wire-free styles are soft and comfortable, especially early on, while flexi-wire styles give a larger bust more lift and shape with a soft, flexible wire that moves with your body. A fitting can help you decide.

What is the difference between a maternity bra and a nursing bra? A maternity bra is designed for comfort and support as your body changes through pregnancy, while a nursing bra adds drop-down clips so you can feed easily. Many styles do both, which is why you will see them grouped together here.
