When you want your wardrobe to keep working exactly as it did before, The Seamless Maternity Brief is what you put on underneath it. No seams anywhere on the garment. No lines through leggings or fitted dresses. No waistband that leaves marks or digs in by the end of the day.


The nylon fabric is light enough that most women describe wearing it as feeling like nothing at all. The high waist sits over the bump and moves with it, comfortably, without needing adjusting. It is seamless enough to sleep in and smooth enough to wear under your most fitted pieces.


It goes with you through the whole of pregnancy.
That is what it is made for.

Size to your pre-pregnancy size. The Seamless Maternity Brief runs from S to XL. The seamless nylon fabric has generous four-way stretch and accommodates bump growth through the whole of pregnancy without needing to be replaced at each stage.


The high waist sits above the bump and rises with it as you grow. In the earlier months it will sit at your natural waist. As the bump grows it begins to sit across the lower belly, which is where it feels most comfortable for most women. The seamless construction means it adjusts to your shape without creating pressure points at any stage.


Because this is a seamless pull-on style with stretch fabric, sizing can feel slightly different to structured underwear. If you are between sizes, go up. The listing notes a 1 to 2cm variance in measurements due to the stretch, which is normal. Full measurements are in the size chart on this page.

The fabric is nylon throughout, with a double layer at the gusset. Nylon is one of the lightest, smoothest fibres available. It sits against the skin without texture or friction, stretches in four directions and returns to its original shape, and does not pill or lose colour through repeated washing.


The double-layer gusset provides an extra layer of coverage at the most sensitive point without adding bulk or stiffness.

Composition: Nylon

Care: machine wash at 30°C. Wash dark colours separately on first wash. Do not soak for more than 15 minutes. Do not bleach. Do not tumble dry. Hang to dry. Low temperature iron only if needed. Do not dry clean.

Will it still fit as my bump grows, or will I need to size up?


The four-way stretch nylon accommodates the changes
in your waist and hips through the whole of pregnancy
without losing its shape. The high waist sits over
the bump and rises with it rather than digging in or
rolling down as the bump grows. Most women wear the
same size from the first trimester to full term. If
you are between sizes, go up, and the stretch will
handle the rest.


Is the fabric breathable enough?


This is a finer, lighter weight nylon specifically constructed for a naked feel against the skin. It sits without friction rather than clinging or trapping heat against the body. It is not the same
as thick shapewear nylon. That said, if you run particularly warm, the cotton-based options in the collection will breathe better overnight.


Will it go see-through when it stretches over the bump?


No. The fabric is confirmed as resistant to deformation through repeated wear and washing, which means it holds its structure and opacity even when stretched over a full-term bump. The four-way stretch returns to its original shape rather than thinning out.


How is this different from the other underwear in the collection?


The Seamless Maternity Brief is about invisibility and comfort under clothing, with a high waist that sits over the bump. The Bump Support Short has a V-shaped crossover waistband that sits beneath the bump and lifts it from below, a longer leg to
prevent thigh chafing, and a 100% cotton gusset. The Brief is what you wear when you want to forget you have underwear on. The Short is what you wear when you need the bump to feel actively supported through a long day. Many women keep both.

"I've tried so many maternity leggings and nothing comes close. The waistband actually stays up and doesn't dig in at all. I'm 28 weeks and I've been wearing these every single day."
