THE ROLE OF WOMEN'S LINGERIE
Women's lingerie is one of the most powerful "weapons" in the arsenal of every woman who wants to look attractive, confident, and irresistible. It is an essential part of every woman's wardrobe, and at SIA Underwear we say: "The day begins and ends in lingerie!" Women's lingerie is constantly present in our daily lives – whether we're at work, at home, or on vacation. We believe that every woman creates her image by choosing her lingerie for the day, deciding what social role she wants to play. Choosing sporty styles like cotton briefs for workouts or hiking suggests comfort and an active lifestyle. If we choose sexy women's lingerie like red lace thongs, we step into the role of seductress – or at least feel that way. If we prefer functional styles designed to protect parts of the body from chafing or to shape problem areas, it means we simply value comfort and freedom of movement.
HISTORY OF WOMEN'S LINGERIE
The history of women's lingerie has undergone tremendous development, with each era bringing a true metamorphosis in its appearance. We can trace its beginnings to the fig leaf described in the Garden of Eden. The linen and leather loincloths of antiquity gave way over the centuries to the voluminous undergarments of the Middle Ages, which covered far more of women's bodies than today's outerwear. Of course, lingerie evolved over the years, but the major transformation began in the early 19th century, when all the petticoats, chemises, corsets, and culottes gradually reduced to bras and briefs made from luxurious satin fabrics – the prototype of modern intimate apparel.
Today, the variety of styles is endless and continues to evolve. Just 20-30 years ago, lingerie was available in only a few basic colours – white, beige, black, and occasionally navy or red. In our time, new technologies, fabrics, colours, and patterns constantly emerge to meet the ever-growing expectations and needs of customers. The fabrics used for quality women's lingerie are now highly elastic and gentle on the skin, while lace designs become ever more beautiful and alluring. On the market, you can find incredible offerings featuring bold combinations of printed fabrics with multiple laces, elastics, crystals, and accessories.
TYPES OF WOMEN'S LINGERIE
Modern women's lingerie offers an enormous variety of styles, each designed to meet different needs and preferences. At SIA Underwear, we offer a complete range of bottoms, tops, and sets.
Briefs
The classic and most popular women's lingerie style. Briefs provide full coverage and maximum comfort for everyday wear. Available in low, mid, and high-rise options to suit different preferences and body types. Ideal for women who value comfort above all else.
Brazilian Briefs
The style that combines the comfort of briefs with the sex appeal of thongs. Brazilian briefs have a narrower back that elegantly accentuates curves without showing through clothing. This is the best-selling item in our online store.
Boyshorts
Comfortable and practical, boyshorts offer maximum coverage and are perfect for active women. They're ideal for sports, lounging at home, or wearing under looser clothing. Polyamide boyshorts are especially popular for their softness and silky feel.
Thongs
The minimalist choice for women who want their underwear to remain completely invisible under clothing. Thongs are perfect for tight trousers, dresses, and occasions when you want to feel seductive. At SIA Underwear, we offer thongs in various fabrics – from cotton for everyday wear to lace for special moments.
Camisoles
An elegant top that can be worn alone or as part of a set with bottoms. Camisoles are ideal for women who don't wear bras but want light support and coverage. We offer cotton, tulle, and lace camisoles for every taste and occasion.
Lingerie Sets
The perfect choice for women who love a complete, harmonious look. Women's lingerie sets include matching tops and bottoms in the same design, colour, and fabric. Ideal as gifts or for special occasions.
Bralettes
Short tops that provide light support and can be worn under sheer blouses or on their own at home. Bralettes are a comfortable alternative to bras for women with smaller busts.
Garters
A sexy accessory that adds the finishing touch to any lingerie set. We offer classic leg garters and bridal garters.
Functional Underwear
Specially designed women's lingerie with practical purposes. This category includes slips for dresses and skirts that ensure a smooth silhouette, as well as anti-chafing shorts – an indispensable companion during hot summer months. Functional underwear protects the skin from discomfort and irritation while remaining invisible under clothing.
FABRICS FOR WOMEN'S LINGERIE
Choosing the right fabric is essential for the comfort and durability of women's lingerie. At SIA Underwear, we use only high-quality European materials.
Cotton
The most natural choice for everyday women's lingerie. Cotton is breathable, moisture-wicking, and hypoallergenic, making it ideal for women with sensitive skin. Cotton styles are suitable for all seasons and provide maximum comfort throughout the day. At SIA Underwear, we use high-quality stretch cotton that maintains its shape after repeated washing.
Polyamide (Microfibre)
Polyamide is a high-quality synthetic fabric distinguished by exceptional softness and a silky feel. Unlike polyester, polyamide is more durable, more elastic, and more comfortable against the skin. Women's lingerie made from polyamide fits the body like a second skin, dries quickly, and doesn't retain odours. The fabric is resistant to repeated washing, retains its colour, and doesn't shrink. It's the ideal choice for tight trousers, leggings, and fitted dresses because it's completely invisible under clothing.
Lace
The symbol of luxury women's lingerie. Lace styles are elegant, seductive, and perfect for special occasions. We use quality European laces that are soft and don't irritate the skin. Lace adds an extra touch of femininity and confidence.
Tulle
A sheer, light, and airy fabric with a luxurious appearance. Tulle styles create a feeling of lightness and are ideal for warm months. They can be decorated with embroidery or appliqués for a more refined look.
CHOOSING QUALITY WOMEN'S LINGERIE
Hidden under clothing and invisible to others, quality women's lingerie is an inexhaustible source of confidence and sex appeal for every modern woman. It's with her all day, and choosing the right style, set, bodysuit, or just bottoms is key to her self-confidence and sense of comfort. Quality is determined by several main criteria:
- modern design with current seasonal shapes, colours, and patterns
- quality materials and accessories
- comfortable fit and true sizing
- precise craftsmanship
Lingerie should be not only beautiful and sexy but also gentle and safe for our skin and body, preferably made from natural fabrics dyed with harmless dyes.
The best women's lingerie is that which creates the feeling of wearing nothing at all. This means the fabric is high quality, the fit and craftsmanship are at the right level, and we've chosen the correct size.
HOW TO CHOOSE THE RIGHT WOMEN'S LINGERIE SIZE
Choosing the right size is key to comfort and a good fit. Here are some tips:
Measure Yourself Correctly
Use a soft measuring tape to measure your waist circumference (the narrowest part) and hip circumference (the widest part). Compare your measurements with our size chart.
Choose According to the Cut
Different styles have different cuts. Brazilian briefs and thongs usually fit more snugly, while briefs and boyshorts are more relaxed. If you're between two sizes, choose the larger one for greater comfort.
Pay Attention to the Fabric
Cotton items are less stretchy than those made from polyamide. If you're choosing a cotton style, make sure the size is exact. Polyamide and tulle styles are more elastic and more forgiving of slight size variations.
WOMEN'S LINGERIE IN PLUS SIZES
At SIA Underwear, we believe every woman deserves beautiful and comfortable lingerie, regardless of her size. That's why we offer women's lingerie in sizes from S to 6XL. Most of our styles are available in plus sizes 3XL, 4XL, 5XL, and 6XL, and if you can't find your size, we can make lingerie to your individual measurements.
The privilege of being a manufacturer is that we can sew almost any style in a size specified by the customer according to their personal measurements. Constructing and sewing to individual sizes is a challenge we've been successfully meeting for years. The conditions are described in the "Plus Sizes" category.

The SIA Underwear brand has been on the Bulgarian market for more than two decades. The styles in our collection stand out for their luxurious appearance, quality craftsmanship, and attention to detail. The brand's team puts daily effort into making the products comfortable, beautiful, and unique not only in appearance but also in durability.
The approval process for each new style before it goes into production is slow and includes trials and adjustments to the technology and design until the optimal version is achieved, with each step filled with great desire and creativity. The journey of lingerie as it reaches you, our customers, is long. For each style, we at SIA Underwear strive to select the most suitable and quality fabrics and auxiliary materials, try different combinations, and only when we're truly satisfied with the final result does it reach you.
Our all-female team understands the difficulties of finding the right lingerie that is comfortable, beautiful, provocative, and sexy. The right choice of the most suitable style and size can affect comfort and mood – or the opposite. If the new lingerie you recently bought turned out to be insufficiently stretchy and actually too small, but you were still tempted to wear it under elegant clothes for a formal occasion, the result will be that during the event you'll feel uncomfortable and self-conscious instead of having fun. Then you'll surely dream of the gentle touch of your favourite brand with proven quality, in which you feel so comfortable you don't even notice it.
SIA Underwear creates women's lingerie for every woman, of every age, in every size, with the idea that she should feel comfortable, seductive, and irresistible. The pleasure of a job well done is expressed in the smiles of the many satisfied and loyal customers we've won over the years of dedicated work.
HOW TO CARE FOR YOUR LINGERIE
Proper care extends the life of your items and preserves their qualities. Here are the basic rules:
Washing
Always check the label for recommendations. Cotton styles can withstand higher temperatures up to 40°C, while delicate fabrics like lace and tulle require hand washing or a delicate cycle up to 30°C. Use a mild detergent and avoid bleach, which can damage fibres and colours.
Drying
Never use a tumble dryer – high heat deforms elastic fibres and shortens the garment's life. Let your lingerie air dry in the shade, away from direct sunlight.
Storage
Arrange your lingerie in a drawer, folding it carefully. Avoid pressing lace and tulle styles under heavier clothes. Separate light colours from dark to prevent colour transfer.
Special Tips
For polyamide items, avoid contact with creams and oils immediately after application – they can leave stains. Wash lace styles in a special laundry bag to prevent snagging and stretching.
