Just as an FYI - it is possible to wash our silk blend tees and tanks. We recommend dry clean only because this is a delicate process and could definitely destroy / shrink the garment. Some of us on the team just machine wash cold on "hand wash" cycle with Woolite and then hang to dry. You will probably see some shrinkage (they are cotton / silk) and I definitely recommend following our care labels first - we can't be held liable for washing a tee that says "dry clean only" on the instructions, but many people do wash them without incident. Wash at your own risk but it is definitely possible without wrecking the garment. If you wash them and dry them or apply any heat you will definitely shrink them a full size.
