Light blue long-sleeved shirt by DRESSTERIOR, shell buttons - Brand: DRESSTERIOR - Size: 36 - Color: Light Blue This is a very elegant shirt from DRESSTERIOR. The tag is faded and unreadable (see photo 4), but it comes with spare buttons. I believe the material is cotton. The weave of light blue and white threads is very beautiful. The item itself has been dry cleaned and carefully stored, so I think it's in good condition. Thank you for looking.
