Beginner's Guide to Beautikini Period Underwear

An increasing number of women are adopting a new approach to menstrual management, abandoning traditional options like menstrual cups, pads, or tampons in favor of specially designed period underwear. This trend is known as “free bleeding.”

You might be curious, “Just underwear?” Let us tell you the reasons behind it.

What is Period Underwear?

Period underwear is specifically designed lingerie for menstruation, intended to replace traditional disposable products like pads or liners. While some women may choose to use period underwear on lighter flow days and switch to it as a backup on heavier flow days, many have fully embraced this new solution. The appearance and feel of period underwear are similar to regular lingerie, avoiding a bulky sensation. However, it incorporates additional layers and special fabrics in the pelvic area to absorb menstrual blood. These undergarments can be washed, reused, and worn throughout the entire menstrual cycle.


How Period Underwear Works

It effectively absorbs and protects against menstrual flow by utilizing absorbent materials capable of handling the equivalent of three sanitary pads, maintaining a comfortable moisture barrier, and preventing leaks or stains. If you’re hesitant about trying this new method, many users start by using period underwear on lighter flow days or as backup protection and gradually transition to full-time use. Beautikini currently offers a “1 Order 3 Sizes” promotion for period underwear. If your first order is a specific size, you’ll receive one size up and one size down with your purchase, providing customers with more options within the same order.

Care Instructions for Period Underwear

Step 1: Soak

After removing your period underwear, soak them in cold water or rinse them. This helps quickly remove residual menstrual blood, reducing the likelihood of stains. Cold water is more suitable, as hot water might cause blood to coagulate.

Step 2: Wash

If machine washing, place the period underwear in a washable mesh bag and use a gentle detergent for a delicate cycle. Avoid using bleach or harsh detergents to prevent damage to the fabric and maintain its absorbency. Handwashing is another gentle option that can extend the underwear’s lifespan.

Step 3: Drying

Do not put period underwear in the dryer, as high heat may damage the fabric’s elasticity and absorbency. Instead, lay the underwear flat or hang them to air dry. Avoid direct sunlight exposure to prevent damage to fabric color and texture. Natural air drying helps maintain the fabric’s integrity.

Step 4: Treatment

If concerned about stains or lingering odors, although period underwear is designed to be stain-resistant, you can soak them in a mixture of vinegar and water before washing. Vinegar has antibacterial and deodorizing properties, helping keep the underwear clean and fresh. Ensure thorough rinsing after washing to avoid any residual vinegar scent.


Following these simple care steps ensures that your period underwear remains comfortable, hygienic, and durable throughout its use.
