Duoplex fabric is undeniably the best fabric to use for the cups and front frame because it provides great support. It can be used on its own without having to line the cups. It is also a reversible fabric – shiny on one side and matte on the other. Duoplex is a 100% polyester non-stretch stable knit fabric, and it is what we use in our bra kits together with power net.
Please note: This fabric is sold by the piece 65cm x 75cm (ample for one bra)
