Best Type of Underwear for your period

The best type of underwear for your period is whatever you feel most comfortable in and is most similar to your regular underwear. Generally a hip hugging style in cotton / lycra will work well as it's breathable, absorbent and will fit snugly.

Wearing comfortable, well fitting underwear is always important no matter what time of the month. There's nothing more uncomfortable than baggy, saggy pants which wriggle around under your clothes and potentially climb between your bum cheeks!

When you've got your period, this is even more critical to feeling good and being able to go about your day. If you use disposable or reusable sanitary pads, your knickers need to fit well in order to stop your pad moving around.

Alternatively you might want to consider wearing period underwear, a new type of menstrual product, specially designed to protect from menstrual blood. It's also available as period swimwear.

What is Period Underwear?

Period underwear is knickers made from layers of material which are moisture wicking and absorbent. The layers absorb your menstrual flow and are also leak proof which means you stay feeling dry and secure.

If you choose the correct absorbency level of period pants, you won't need to use any additional period products for extra protection. Period undies can generally hold 2 tampons or menstrual cups worth of period blood.

Period Underwear can be washed in the washing machine, but it's important to note that they should be washed in cold water. That's because menstrual blood is a protein stain, and washing at higher than blood temp will 'set' the stain.

Types of Period Underwear:


Period Briefs

Shop Period Briefs

There are lots of different styles of period briefs available. We'll discuss specific designs shortly but generally they fall into categories based on rise (i.e. low-rise bikini style, mid waisted bikini styles such as our Sassy or Lace-topped period underwear and high-waisted options).

If you're looking for plus size period pants, we have a range available in sizes 4 to 24!

In addition, period briefs will also come in different absorbency levels. Products such as period thongs are suitable for light days or spotting. Most period pants are suitable for 'regular' wear or normal flow as they will hold up to two tampons worth of blood. However heavy flow period briefs will hold around 4 tampons worth of blood and can be worn all day, even on heavy days.

When considering which period underwear brand to buy, you should consider where their absorbency and leak proofing is contained. Some brands ONLY have absorbency in the gusset area, which can lead to leakage. Cheeky Pants have got absorbency to the front and rear waistband as standard.

Bamboo Period Underwear

For some people, the feel of their knickers against their skin is super important, especially if they suffer from sensitivity or irritation around their vulva. If you're looking for a pair of period pants which are extra soft, then we can highly recommend bamboo period underwear.

Bamboo is naturally anti-bacterial too, which is great if you tend to suffer from infections or thrush.
