Vintage 80s New Sirena Swimsuit Blouson Top L 14. 80s Sirena swimsuit new with tags still attached. Even though it is new and still has the tags there are a couple of scratches in the fabric, one on the turquoise waistband and just below that on the purple. These are scratches and do not go all the way through the fabric so they are not holes. know this is a swimsuit but I still feel like it could use some legwarmers and a sweat band, a la Olivia Newton-John or Jane Fonda. This one piece swimsuit has a blouson top, a turquoise gathered band across the waist and, according to the tag it is designed to ?shape and flatter your body?. Of course it is swimsuit material so it is very stretchy, but laying flat it measures 32 inches end to end, 18.5 inches armpit to armpit and 13 inches across the waist. Tag size 14 But I would say it?s closer to a modern size large
