Isotoner is best known for their gloves made of a stretch material. Bali introduced these bras in 1990 featuring the four-way stretch isotoner fabric, advertising them as extremely comfortable. I don’t know how long they remained on the market. Wirefree and full-figure models were also available.
This bra is very worn out. The material has lost most of its stretch. The underwire cups are unlined and seamless. Leotard back.
