The final thing is regarding lining. Make sure your lining has the same characteristic as your swimsuit fabric so it has a good stretch in both directions.
We recommend you this fabric of 88%polyester and 18% spandex,100-110gsm lining fabric as your first choice, it is four-way stretch and soft touching also with good colorfastness, you can buy it from us. Another economic fabric is 100% polyester with 100gsm, this is cheaper but not with good stretch, but it is also wildly used.
We can’t mention all the fabrics on this page and it will develop more and more funky fabric along with time, we will catch it!
