Period & Incontinence Underwear – Bikini

(13 customer reviews)



Emflower’s Period and LBL Underwear are certified organic, so there are no nasty chemicals used in the manufacturing process.

The Bikini style has a tighter waistband, but not as tight around the legs than our Hip Hugger style. We prefer to wear the bikini style with a skirt, dress or during the summer months as they are lightweight and breathable.

Wearing organic Period Underwear is better for the planet, your body and your health. Read our blog to find out why.

60 day guarantee that you will love them, or your money back!


Emflower’s Bikini style holds the equivalent of 4 tampons.

For light periods: We recommend changing our Period Underwear every 12-20 hours.

For medium periods: We recommend changing our Period Underwear every 9-12 hours.

For heavy periods: We recommend changing our Period Underwear every 7-10 hours.

Emflower’s Period Underwear will stay in great shape for up to 90 washes (approximately 3 years based on wearing them 2-3 times per cycle), with proper care.

Models are wearing a size XS/6 and 2XL/16

How To Wash Period Underwear:

  1. Rinse your Period Underwear in cold water within 24 hours. You can also soak your Period Undies in a bucket of cold water with a little bit of laundry detergent until you are ready to wash them.
  2. Put your Period Underwear into a Laundry Wash Bag that can be zipped closed, then into the washing machine.
  3. Wash your Period Underwear on a warm wash (around 40 degrees Celsius).
  4. Hang dry your Period Undies. Do not put them in a dryer or iron them.
  5. Do not use fabric softener or bleach on your Period Underwear

Outer Materials: 70% Bamboo Fiber & 30% Vicose
Crotch Materials: 70% Bamboo Fiber & 30% Vicose
Inner Material (2 layers): 80% Cotton & 20% Polyester; Breathable PUL

How many hours can I wear my Period Underwear for?

Well that depends on how heavy your period is. Our Period Panties hold up to 4 tampons worth, which is equivalent to 1 day with a medium to heavy period. If you generally use more than 4 tampons during the day, make sure you keep a spare pair of Period Undies in your bag just in case.

Does Period Underwear stain?

To decrease the chance of your Period Underwear staining, make sure you rinse or soak them within 24 hours after wearing them. If you are not doing washing for a couple of days, leave them soaking in a bucket of water with a little bit of laundry detergent.

How many pairs of Period Underwear do I need?

That depends on how long your period lasts, and how heavy it is. We recommend changing your Period Underwear each day and night. So if your period usually lasts 4 days, we would recommend 8 pairs of Period Underwear. When your period is light you could easily get away with wearing them for up to 24 hours.

Can I wear Period Underwear with other menstrual products?

Yes you certainly can. For those with heavier periods, we recommend pairing your Period Undies with a Reusable Menstrual Cup for that extra protection. Our menstrual cups are made from medical grade silicone, can be worn up to 10 hours and last up to 16 years!

They can also be worn with tampons and pads, but in all honestly they don’t need to be. They have 4 layers of protection so you should be more than fine to just wear your Period Underwear by themselves.

Can I wear Period Underwear Swimming?

Unfortunately you cannot wear your Period Underwear swimming. Those 4 layers holding it all in will definitely leak out into the pool. We recommend using a Reusable Menstrual Cup when you go swimming, as you will be fully protected from leaks.

  1. Sarah

    So comfy!! These girls knew what they were doing when choosing this style! And the donation to Zonta. Well done team

  2. Danielle

    I was super skeptical about trying this product as my period has always been on the heavier side. I’ve had my fair share of period horror stories so when I tried these panties I was going in blind and not expecting much. BUT, these panties have seriously changed my life! I wore them halfway through my cycle for 24 hours and there were ZERO leaks. I even had bathroom breaks throughout the day to check if even a little had gone through and to my amaze- absolutely nothing!

    They’re super comfy and they don’t feel heavy or like you’re wearing a big nappy (which was one of my biggest concerns). Plus, I love how these are low rise so I still feel super confident in my undies and bra lounging around the house. Will definitely be purchasing more for future use!

  3. Ash

    So comfy and not bulky-feeling at all! I feel like it solves all problems that come with pads — doesn’t feel like I’m wearing a nappy and absolutely no leaks at all. Plus eco-friendly, which is just a great bonus. Absolutely perfect for everyday wear but especially for sleeping in. I’m used to sleeping straight like a plank on my period in fear of leakage but can finally get some good sleep at that time of the month. So good!

  4. Olivia

    As a woman with endo these undies are a life saver and by far the best on the market! Gone are the days of extra pain caused by other hygiene products and so much comfier than other brands, I can not thank you enough 🙂 already ordering my second 3 pack!

  5. Gladella

    Bought these as a gift for my younger sister as i already use the menstrual cup. She absolutely loves these! Fits her perfectly, feels comfortable and easy to wash. She said these saved her during an exam on a day she wasn’t expecting her period ☺️
    Highly recommend!

  6. Eloise A.

    Absorbs quickly and wicks away. Feels secure and leak proof. No odour, I’m impressed. I’m about to use for the second time but I’m very happy with the quality considering I’ve used other brands in the past which cost more than double and these undies are as good if not better!

  7. Cassandra K.

    These underwear exceeded my expectations. I’ve never used them before and didn’t know how I would feel. They were so comfortable and I didn’t feel like I was leaking or wet at all. I used them by themselves days and night and loved them. They have definitely changed my approach to my period and I will be buying more!

  8. Clare K.

    Comfortable & such a great idea to limit tampons & pads in our environment!

  9. June W.

    Great product for my daughter

  10. Brittany Wilsmore

    Haven’t had an issue with leakage from the bikini, but I prefer the brief style as they feel more secure especially when sleeping/laying down.

  11. Jade C.


    For the first 10 years of my period life I had severe discomfort with pads, including chafing that was more like actual burns every month. Changing to ‘organic cotton’ pads for the next 10 years helped but there is still plastic in them, which I found out I’m allergic to.

    Switching to these period underwear has been an absolute LIFESAVER! The past few months of periods have been the most comfortable periods of my life! I’m not exaggerating that, I’ve never been so comfy through that week each month. No chafing, certainly no burning, and no general irritation that comes with having a pad on. I can move around without it being annoying, dance, work out… and there’s none of that grossness when you’re going to the bathroom. Kinda gross but I tested it on one of my heavy days and could run my finger over the inside and it wasn’t even damp! (Gross I know but I couldn’t believe how dry I felt!).

    Washing them out felt a little weird the first few times but you get used to it. Make sure if they’re not going into the wash straight away that you rinse them in warm water or follow the other care instructions that come with them.

    I am a large woman, wearing between 18-22 in clothing and have bought the 3XL. They fit wonderfully.

    I wholeheartedly recommend!

  12. Jade

    I was unsure how the transition away from tampons and sanitary pads would go, but have been pleasantly surprised with the change to the period underwear. The underwear is comfortable and I’ve had no issues with leakage/ smells.

  13. Jo L.

    Fast and happy service. Great product, which I know because I’m a return customer. Thanks you! Always a pleasure 🙏
