Our PVC Clothing I can attest to, as being of very high quality heavy weight pvc material,  (though not heavy at all to wear, quite the opposite).
Scientifically tested and quality control checked, the material is the first of its kind,
its Polish designer's call the material 'Lack', where the polyimide upper material or PVC is attached to elastic stretchable breathable fabric - lycra, or a 'web' underneath.  
This has many bennefits, firstly the garment is breathable making it ideal for clubbing, -  yes, it's specially designed to keep your body temperature on the optimum level, so you never sweat or feel cold any time of the year...
And secondly because the fabric stretches, it means that it is very figure hugging
and very glossy looking.
