Purchased this nice Lands' End tankini for a trip to Mexico.  I wore it a couple of times that week but has been washed and stored in a smoke-free, pet-free environment ever since.  I live in Wyoming where it's very cold and will not be wearing it anymore.  It is in great shape with no flaws.  Fabric is 80% nylon and 20% spandex.  Underwire built-in bra.  Adjustable straps.  Hand wash, line dry.
