Ordered two sizes too small so I could pull it tight and get the needed support (I have F cups) and it fits. I probably would have got a 2X better but it will do. Fabric is thick and not really stretchy, and it is soft on the inside but vinyl-like on the outside. Strings are thick too and good thing because they got a big job ahead of them

The material so much softer than I was expecting. Very stretchy and will fit. Lifts the girls up VERY nicely coming from a 46DD.
