DIRK VAN SAENE rare vintage 90s open sided T Shirt Top 
Beige/tan

Interior tag is missing, fits like a size US Small in my opinion. See measurements in photos.

Both sides are open and lay really nicely on the body. 

Pre-owned, some marks and some small rips, shown in photos. The brand tag is only halfway attached as well. 
The color is closest to the photos on the blue chair.
