No fabric content but probably Lastex
Ruche detail at top of bodice
Bust lined with very basic bra like structure with boning
Straps are adjustable. Hooks on both ends to attached to tabs on inside of front and back
Five elastic rows sewn vertically in back. Elastic is no longer stretchy. Could probably be replaced if you were feeling really industrious
Suit itself still has good stretch
Crotch is in good shape
This style of swimsuit is so great. I think it looks good on everybody!
