Bikinis
Ideal for everyday wear, bikinis offer comfort and freedom of movement. They are the classic choice that never goes out of style – versatile, practical and suitable for any age. We offer them in various materials, colours and designs, with low or high waist.
Brazilian Briefs
They combine the comfort of bikinis with the allure of thongs. Their characteristic cut – more revealing at the back – accentuates your curves and creates an elegant silhouette. Brazilians are the perfect choice for women who want to feel sexy without sacrificing comfort.
Boyshorts
Comfortable and practical, boyshorts offer maximum coverage and are an excellent choice for sports, home comfort or wearing under loose trousers. They don't ride up and provide freedom of movement.
Thongs
Designed to be invisible under clothing, thongs are the perfect choice for elegant dresses and tight trousers. Despite minimal coverage, quality thongs can be surprisingly comfortable. Discover a variety of materials and decorations that will make you feel sexy and confident.
High Waist Styles
Elegant and stylish, these underwear bottoms smooth the tummy and accentuate the waist. They visually elongate the silhouette and are ideal for women who want to feel confident. Perfect for wearing under high-waisted dresses and skirts.

HOW TO CHOOSE THE RIGHT UNDERWEAR BOTTOMS FOR DIFFERENT OCCASIONS
The choice of underwear bottoms depends on the clothes you'll be wearing and your activities throughout the day.
For everyday wear
For the office and daily activities, choose comfortable underwear bottoms made from breathable materials. Cotton bikinis or brazilians are an ideal choice. Styles with flat seams won't show under clothing.
For sports and active lifestyle
During physical activity, comfort comes first. Boyshorts and sports bikinis with a wide waistband are an excellent solution – they stay in place and don't ride up during movement.
For tight clothing and elegant outfits
When wearing tight trousers, body-hugging dresses or thin fabrics, choose seamless styles or thongs. For light-coloured clothing, choose nude tones; for dark clothing – black.
For special occasions
For romantic evenings and special moments, choose lace or tulle underwear bottoms. They create a sense of luxury and femininity.
For comfort at home
When you're at home and want maximum comfort, choose soft cotton styles or boyshorts.
Choose the right size
Make sure your underwear is the right size to avoid discomfort and flatter your figure. In SIA Underwear online store, there's a size chart for each product. You just need to know your hip and waist measurements to find the exact size.
Consider the occasion
Choose underwear bottoms that are appropriate for the occasion. For everyday wear, choose comfortable and practical styles, and for special occasions – elegant and alluring lingerie.
Match your clothing
Choose underwear that's invisible under your outfit. For tight clothing, choose thongs or seamless brazilians. For light-coloured clothing – nude tones.
Experiment
Don't be afraid to try different styles and colours to discover what suits you best.
EXPRESS YOUR INDIVIDUALITY
Our collection of underwear bottoms is designed to meet the needs of every woman. Whether you prefer classic styles or bold designs, we have something for you.
