Fantastic vintage Versace - the label/ logo design + the cut & pattern of the weave suggest this is very much from the 1980s!
The size label says IT44, but I say it is a better fit for UK8 and UK10s. The fit is close to the body/ relatively tight... fab worn with high waisted skirts/ trousers.
There is no fabric label. I would say that it is a wool mix but can't be sure.
In good vintage condition.
