Cover your growing bump with stretchy, breathable comfort and flexible tummy support. Enjoy a brief that offers full, lightweight coverage while providing a breathable layer for underneath all your favourite clothes.  With a waistband that comes right up to your bust, you won't feel exposed in your growing, glowing shape. 

Available in black, white and nude, this soft full brief is the perfect base under all your sheer outfits, or just for that extra bit of comfort in moving through your busy life. If you’re finding during your pregnancy that your tops are a bit short and riding up, this brief will be an added layer to make you feel comfortable. It covers the tummy without putting pressure on it, and can be worn comfortably through each trimester.

Made of cotton rich fabric, you'll love its breathability and ability to keep you cool in the summer and warm in the winter. Natural insulation properties in the fibres creates added warmth against the skin, so this piece is a cosy maternity layer for winter. Cotton is also kind to the skin, as is our seam-free, tag and label-free technology, for that soft comfort that you love from B Free.

The maternity undies are awesome. Super comfy, don't fall down, give you a smooth shape with no undies lines. Definitely recommend.

Comfort and quality

So good I bought another pack! These briefs offer full comfort and coverage, for when you just want/need your undies to stay UP. There's having to strategically hike them up. The material is such good quality, soft but supportive, which I found definitely takes some pressure off the lower back, and also helps when I'm having "achy" days - the great stretch of 2020. Highly recommended.

Perfect pregnancy underwear

I love this underwear! All of the other pieces I was wearing kept rolling down under my belly or leaving elastic marks, these are perfect for a growing belly with lots of stretch and lots of comfort. The quality is also fantastic and I highly recommend them for any pregnant women looking for some truly comfy undies ^_^

Highly Recommend

Soft and comfortable. They don't dig in to my skin and sit comfortably above my bump. I wish I had purchased these earlier. In regards to purchasing these, it was easy and simple. Postage was quick, despite being in the COVID lockdown period, which was really surprising.

Just what I have been looking for!!!

The most comfortable underpants and feel so much more comfortable not worrying if my pants have slipped down and shirt up. Particularly at work. Wish I had got these first time around.

Best pregnancy purchase

The underbrush underwear has been my favourite (and most appreciated) pregnancy purchase so far. At about 16 weeks along I started to find anything sitting across my stomach caused discomfit. I searched for weeks for a solution until I came across these. I purchased the 3 pack and will be purchasing more! At six months pregnant these are not only comfortable, they also slightly shape my bump (smoothing out some annoying lines) and provide slight support (perfect for night in particular).
