Lining, Stretch & Finish Notes
Bikinis are commonly made from nylon, polyester, Lycra-type stretch fibers, or spandex blends, but the listing should confirm the exact fabric composition.
Avoid pulling, abrasion, and unapproved washing methods that could loosen decorative elements.
Sequins, rhinestones, glitter, or reflective details can catch light strongly and may require gentle handling.

I wanted a cute bikini that wouldn’t pull a Janet Jackson on me while playing in the ocean. This bikini was great. It was cute and comfortable. It held up really well and it is ready for my next sunny vacation!

I really like this suit. I like how the bottoms are adjustable. I was in a car accident in 2019 and have a slight deformity in one of my hips from the seat belt. So it was nice to be able to have the different sides adjusted differently.
