BIKINI BRIEFS
Bikini-cut panties from a Bulgarian manufacturer in sizes S-6XL. We offer cotton, lace, microfiber and tulle bikini briefs — with low or high waist. All styles feature comfortable cuts made from European materials that remain invisible under clothes. Can't find your size? We make custom orders.
The choice of fabric determines comfort and purpose. At SIA Underwear we use high-quality European materials.
Cotton briefs
Cotton bikini briefs are the most popular choice for everyday wear. Cotton with elastane is breathable, absorbent and hypoallergenic — ideal for women with sensitive skin. We offer cotton briefs with low and high waist, plain or with decorative lace. Cotton styles keep their shape after multiple washes and are suitable for all seasons.
Microfiber briefs
Microfiber bikini briefs are the perfect choice under tight clothes. Polyamide is smooth, stretchy and durable — it fits like a second skin and remains completely invisible under pants and dresses. Microfiber briefs dry quickly after washing and don't lose their shape. We offer thin styles for summer and denser ones with a shaping effect.
Lace briefs
Lace bikini briefs are a symbol of femininity and elegance. We use quality European lace that is soft and doesn't irritate the skin. Lace styles can be made entirely of lace or combined with cotton and microfiber. A perfect choice for special occasions or when you want to feel more confident.
Tulle briefs
Tulle bikini briefs are light, sheer and extremely comfortable. Polyamide-based tulle with elastane fits delicately and creates a feeling of lightness. Ideal for warm months under thin dresses and skirts. Tulle styles are elegant and feminine without sacrificing comfort.
Waist height determines how briefs fit and what clothes they're suitable for.
Low-waist briefs
The classic choice for everyday wear. Low-waist briefs are suitable for jeans and pants with a low waistband, as well as shorter tops. They don't squeeze the belly and allow freedom of movement. Preferred by women who seek minimalist design and light comfort.
High-waist briefs
Ideal for women who want extra comfort and tummy coverage. High-waist briefs create a smooth line under dresses and skirts, visually elongate the silhouette and provide light support. An excellent choice for postpartum women or those who prefer more security.
Tip: Choose brief height according to your clothes — low waist under low pants, high waist under dresses and skirts with a high waistband.
The right briefs flatter your figure and provide all-day comfort.
Slim figure — all styles are suitable. Panties with lace and decorative elements add volume and femininity. Tulle styles are also an excellent choice.
Wide hips — high-waist briefs balance proportions and create a harmonious silhouette. Avoid tight elastic bands that dig in and pinch.
Tummy area — high-waist briefs provide comfort and light support. Microfiber styles with a shaping effect sculpt the silhouette without uncomfortable pressure.
Pear-shaped figure — briefs with wider side coverage and no tight elastic on the thighs. High waist draws the eye upward.
Postpartum — soft cotton briefs with high waist that don't press on the belly. Choose one size larger for maximum comfort in the first months.
Brief color matters for invisibility under clothes and personal enjoyment.
Nude — the universal choice that remains invisible under any clothes. Ideal under white, light colors and thin fabrics. A better option than white even under white clothes.
Black — a classic for everyday wear and under dark clothes. Practical, elegant and easy to care for. Black briefs are an essential wardrobe basic.
White — fresh and youthful, suitable for summer. But under white clothes, nude is a better choice — white sometimes shows through.
Colors and prints — for mood and personal pleasure. Floral prints, dots and pastel colors add joy to everyday life. Wear under thicker and darker clothes.
Red, burgundy, black with lace — for special occasions and romantic moments. Pair with a matching camisole for a complete look.
By purpose
For everyday wear choose cotton briefs with elastane — breathable and comfortable all day. For special occasions — lace or tulle styles. Under tight clothes — microfiber briefs in nude that remain invisible.
By size
Measure your waist and hip circumference with a soft measuring tape. Compare your measurements with our size chart. If in doubt between two sizes, choose the larger one for more comfort. Cotton styles are less stretchy than microfiber — keep this in mind.
By fabric
Each fabric has different stretch. Cotton is firmer and requires an exact size. Microfiber and tulle are more flexible and tolerant of slight variations.
We offer women's briefs in sizes from S to 6XL. For larger sizes or specific requirements — we make custom orders.
Which women's briefs are most comfortable for everyday wear? Cotton with elastane in the right size. They are breathable, soft and suitable for extended wear.
What briefs should I wear under light clothes? Briefs in nude microfiber. Avoid white under white — nude is more invisible.
How do I know what size I need? Measure your waist and hips and compare with our size chart. If in doubt — contact us for advice.
What briefs are suitable under tight pants? Microfiber briefs without elastic bands or with flat seams. They don't show under fitted clothes.
Do you offer women's briefs in plus sizes? Yes, most styles are available from S to 6XL. We also make custom orders.
Made in Bulgaria — every style is created in our facility with quality control.
European materials — we work with fabrics from Italy, Greece and Turkey.
Sizes S-6XL — women's briefs for every figure, with custom sizing available.
25 years of experience — since 2000 we create underwear that combines comfort and quality.
