FAQs

Are all Hotmilk maternity briefs suitable for pregnancy?

Yes, our maternity briefs have been designed to accommodate your growing bump. We have bikini options such as Temptation, Warrior, Show Off and Ture Luxe that will sit comfortably under the bump and super soft mid-cut and over-the-bump options like My Necessity and Serenity Bamboo. We always suggest buying a few different styles as what you like to wear may change throughout your pregnancy and motherhood journey.

Why Should I Choose Bamboo Maternity Underwear?

There are a few reasons why we love bamboo briefs. Bamboo blends are ultra-soft to the touch and gentle on sensitive skin. Bamboo is breathable, thermoregulating and moisture wicking, this all helps to keep you fresher for longer, and best of all, Hotmilk bamboo is sourced from FSC-certified sustainably grown crops. My Necessity and Serenity maternity briefs have been crafted from super soft bamboo to nourish a pregnant and postpartum body.

How does a leakproof brief work?

Hotmilk's reusable leakproof maternity briefs provide a solution to manage everyday leaks. Designed with four layers of protection to keep you protected and comfy.

- Layer one is a blend of breathable cotton and sits against the skin. This layer pulls liquid away from the body.

- Layer two is the most absorbent and holds the liquid pulled from the body.

- Layer three is leakproof looped towelling that works as a barrier capturing any remaining liquid.

- Finally, layer four has a special leakproof barrier to keep you looking dry and leak-free.

What is the difference between maternity underwear and regular?

Maternity underwear is specifically designed to accommodate a growing belly and changing body during pregnancy, offering extra support and comfort. Our pregnancy underwear features stretchy, breathable fabrics and wider waistbands to accommodate expanding bellies. Regular underwear may not provide the same level of support or adjustability needed during pregnancy compared to Hotmilk maternity underwear.

When should I start wearing maternity underwear?

It's recommended to start wearing maternity underwear as soon as regular underwear becomes uncomfortable or doesn't fit properly due to pregnancy. For most women, this transition occurs during the second trimester as the belly begins to grow. Opting for maternity underwear ensures comfort and support throughout your pregnancy journey.
