Nelson Swimsuits has its humble beginnings in 1958 when Mr. Nesim Hason started yarn production with a crew of 30 under the name of HAS ON. Mr. Hason who was already one of the most important persons in the textile industry, then led his company to become the first producer of ready-made garments in Turkey in 1979. By then, HAS ON was a relative giant in the industry with 700 employees producing in all areas of textile. In fact, HAS ON was the largest textile producer of Turkey making everything from yarn to fabric, undershirts to socks, and dresses to jackets.

As the yarn production expanded into new areas including mus, HAS ON added swimsuits to its capabilities in 1972, thus creating the foundation of what went on to become Nelson today. By that time, HAS ON was a conglomerate made up of ten companies. In 1981, Nelson was officially formed as an independent company solely focused on swimsuits, when the ten companies under HAS ON were spun off.

Today, under the leadership of Chairman Moris Eskinazi, Nelson continues to be one of the largest swimsuit producers in Turkey with a yearly production capacity of 750 thousand swimsuits. Beyond its dominance and reputation in the domestic market, it is also a significant exporter to major brands in Germany, France, Spain, and Israel. Some of the major collections that have included Nelson- produced swimsuits are Zara™, Victoria's Secret™, Calvin Klein™, Kindy™, Hugo Boss™, Donna Karan™, Juicy™.
