The Brazilian



Our cheekiest cut of all.

For those days you're flowing on the lighter side.

Flow: Light = 10ml / 2 regular tampons.

Light: In the days leading up to your cycle, or the days leading out. 


Try risk free for 60 days*

As a first-time customer, you can try one pair of undies for 60 days risk-free. If you don’t like how they function, we will happily give you your money back (minus the cost of shipping).

Unfortunately, garments that have been worn can no longer be returned due to sanitary reasons. And you know, the market for second-hand underwear isn't all that flash!

So, we will require a brief explanation of the reason for your request.  The trial applies to one worn garment only.

No further refunds, credits or exchanges can be given on any additional worn or washed underpants.

Out of stock items

Current waiting time for out of stock items: less than 2 weeks (14/11/23).

Shipment of your in-stock items may be delayed until your pre-order item is ready for shipping. To ensure faster delivery of your in-stock items, we recommend making two separate orders - one for your pre-order items and one for your in-stock items.


Formulated with organic cotton and nylon made from recovered ocean plastics, these underpants whisk moisture away from your body (and plastics away from the turtles!), keeping you dry and "good karma'd" all period long.

Love it. Comfortable, does the job. Only downside is how delicate the lace part is, it frays quite easy.

Hi there, thank you for your feedback. We are glad to hear that you love the Brazilian and find them comfortable. Although we recommend washing them in a garment bag the lace should not fray. It seems like you have received a faulty pair. Please reach out to customer service @ and they will be able to sort out a replacement pair.

Wunderthings Brazilian is Brilliant

Love the style and cut. A little sexy with practical allows for comfort and confidence in those early days. Probably should have got a size up though :/. Might have to purchase more!

so comfortable and great fit

i wanted to wait to review these until I had used them a couple of times and now that I have. They are great, I have actually found that they dont show a panty line either and are also great to use for gym because they are great with sweat not just your period. So a great all round underwear and super comfortable. defintely go up one size if you find you are sometimes on the fence with sizes.

The Brazilian

Actual underwear is great and is also great to feel sexy while you have your period however these actual pair do not run to a true size. I bought another pair in a different style and they were correct sizing. If you buy Brazilian go up a size.


Love the Brazilian undies! Seamless, cheeky cut and they look very sexy. I love they aren’t thick and the pad doesn’t go up your back 🙌🏼 so it doesn’t feel like you’re wearing period undies.

The padding was too short in the front but the company has corrected and fixed this issue so I’m yet to see what the new & improved version is like.
