Due to the harsh conditions bathing suits are subjected to, I would recommend using a more durable yarn, such as mercerized cotton or a cotton/rayon/nylon blend. You don’t have to line this bikini, but it with help with the way the bikini feels against your skin.
To make sure the yarn you have chosen will be able to stand up to the test of time, make a sample swatch, wash and dry it several times and check for any warping.

This pattern is for Intermediate and Experienced crochet skill levels.
