Our Story

KOSTAR Feminine Lingerie was founded in 1989 to satisfy the demand of Polish women for high quality lingerie. With a group of skilled workers and seamstresses along with the help of advanced technology in production, we continue the tradition of offering products of extraordinary finish and design. Every piece is made in Poland and is hand-crafted, not mass-produced. We are a family owned company and we take an individual approach to each piece of lingerie made. The entire range is manufactured in a variety of sizes and colors in accordance with the highest European standards. Our alphabet does not end with G. We produce bras in a wide variety of cup sizes ranging from A to K and bands from 28 to 50. This variety also extends to the nursing and maternity collections. The company headquarters and production site are located in Bialystok, Poland. We pride ourselves on being a lingerie manufacturer whose production process takes place in Europe, from start to finish.



Each of our products are hand-crafted with quality, aesthetics and design in mind. We aim to create an unique piece of lingerie that is feminine, comfortable and perfectly shaped. We are committed to creating lingerie designed to empower women to feel confident and beautiful.


We offer a wide selection of women’s lingerie that comes in a full range of sizes (S-XXXL). Our selection includes push-up bras, soft bras, padded bras, semi-padded bras, maternity and nursing bras, speciality post surgery bras, panties, thongs, briefs, bodysuits, corsets, garter sets and accessories.
