What are bikini briefs?

Bikini briefs are a mid-rise underwear style that offers moderate front and back coverage. They're cut to sit just below the hips and work well under most outfits—making them a comfy go-to for everyday wear.

Are bikini briefs suitable for all body types?

Absolutely. Bikini briefs are a universally flattering shape that suits a wide range of body types. With a variety of cuts and fabrics, you can find a pair that hugs in all the right places without digging or pinching.

Which materials are best for bikini briefs?

Cotton is breathable and great for daily wear, microfibre offers a smooth, invisible fit under clothes, and lace adds a soft, feminine touch. The right material depends on your needs—whether it’s comfort, style, or something in between.

Can bikini briefs be worn under tight clothing?

Yes—especially seamless or microfibre styles. These create a smooth silhouette with no visible panty lines. They're ideal under jeans, dresses or even workout wear.

How should I care for my bikini briefs?

To keep them soft and supportive, wash your briefs in cold water on a gentle cycle. Use a lingerie bag for delicate fabrics like lace, and air dry to maintain the fabric’s shape and stretch.
