Stores that sell transparent bathing suits include AliExpress, Skinz and Tropical Beach Swimwear. Swimsuits and styles range from partially revealing in certain areas of the swimsuit to being see-through across the entire area.
AliExpress sells a variety of swimsuits and bikinis that are partially transparent while still providing adequate coverage. Skinz offers different transparent and sheer swimsuits and bikinis that become very revealing when wet. Tropical Beach Swimwear uses nylon lycra fabric with varying degrees of transparency. The swimsuits with thinner and finer weaves tend to be more see-through, and darker swimsuits are less see-through. Sheer gauze bikinis are not see-through when dry but become very transparent when wet.
