WOMEN'S UNDERWEAR
At SIA Underwear online store you will find quality women's underwear made in Bulgaria — briefs, Brazilian panties, boyshorts, thongs, camisoles and sets in sizes from S to 6XL. All styles are crafted from European materials in our production facility with attention to comfort and detail.
TYPES OF WOMEN'S UNDERWEAR
Modern women's underwear offers a variety of styles for every need — from everyday cotton briefs to luxurious lace sets. At SIA Underwear you will find a full range of bottoms, tops and functional underwear.
Bottoms
Briefs — the classic style with moderate coverage, suitable for any age. We offer briefs with low and high waist in various fabrics: cotton briefs for everyday wear, lace briefs for special occasions, microfiber briefs under tight clothes and tulle briefs for summer.
Brazilian panties — a style that combines the comfort of briefs with the appeal of thongs. Brazilian panties have a narrower back that flatters your curves without showing under clothes. We offer cotton Brazilian panties, lace Brazilian panties, microfiber Brazilian panties and tulle Brazilian panties.
Boyshorts — comfortable and practical, with maximum coverage. Women's boyshorts are ideal for sports, lounging at home or under loose clothing. Choose from cotton boyshorts, lace boyshorts and microfiber boyshorts.
Thongs — the minimalist choice for women who want their underwear to remain completely invisible. Thongs are perfect under tight pants and dresses.
Tops and Sets
Camisoles — an elegant top that can be worn alone or as part of a set. Camisoles are suitable for women who don't wear bras but want light support. We offer cotton camisoles, tulle camisoles and microfiber camisoles.
Bralettes — short tops with light support that can be worn under sheer blouses or on their own at home.
Lingerie sets — matching top and bottom in one design and color. Women's lingerie sets are ideal as a gift or for special occasions.
Garters — a sexy accessory that adds a finishing touch to any set. We offer leg garters and bridal garters.
Functional Underwear
Shapewear — styles with a shaping effect that sculpt your silhouette and boost confidence under fitted clothes.
Slips — smooth slips for dresses and skirts that provide comfort and prevent show-through.
Anti-chafing shorts — special shorts that protect the inner thighs from friction during warm months.
FABRICS FOR WOMEN'S UNDERWEAR
The choice of fabric is key to underwear comfort. At SIA Underwear we use high-quality European materials from Italy, Greece and Turkey.
Cotton — the most natural choice for everyday women's underwear. Cotton is breathable, absorbent and hypoallergenic. We use cotton with elastane that keeps its shape after multiple washes and allows freedom of movement.
Polyamide (microfiber) — a high-quality fabric with exceptional softness and silky feel. Women's underwear made of polyamide fits like a second skin, dries quickly and remains invisible under tight clothes. Unlike polyester, polyamide is more durable and gentler on the skin.
Lace — the symbol of luxury lingerie. Lace styles are elegant and perfect for special moments. We use quality European lace that is soft and doesn't irritate the skin.
Tulle — a sheer, light and airy fabric. Tulle underwear creates a feeling of lightness and is ideal for summer. Polyamide-based tulle is stretchy and durable.
HOW TO CHOOSE WOMEN'S UNDERWEAR
By Purpose
For everyday wear choose cotton briefs or Brazilian panties — they are breathable, comfortable and suitable for long wear. For special occasions — lace or satin styles that make you feel confident. For sports — cotton or microfiber boyshorts with a wide waistband.
By Outfit
Under light or tight clothes wear nude microfiber underwear without elastic bands — it remains completely invisible. Under dark clothes any color works. Under dresses and skirts add a slip for a smooth silhouette.
By Size
Measure your waist and hip circumference with a soft measuring tape. Compare your measurements with our size chart. If you're between two sizes, choose the larger one for more comfort. Cotton styles are less stretchy than microfiber — keep this in mind when choosing.
We offer women's underwear in sizes from S to 6XL. If you can't find your size, we can make a custom order — see the conditions in Plus size underwear.
CARING FOR WOMEN'S UNDERWEAR
Proper care extends the life of your underwear and preserves its qualities.
Washing — we recommend hand washing in cool water up to 30°C with a gentle detergent. For machine washing, use a mesh bag and a delicate cycle. Avoid bleach and harsh detergents — they destroy elastic fibers.
Drying — let underwear air dry away from direct sunlight. Don't use a tumble dryer — high heat deforms the fabric.
Storage — store women's underwear in a separate drawer without pressing it. Arrange lace styles carefully so they don't snag on other clothes.
