DressCode. 
The fashion answer is the QR code bc we want to know who is behind the makers and manufacturers of our clothing! The QR code is not just stylish, it is also printed on every laundry label, so you can get to know each of my manufacturers. 
 
Shirt Lui is unisex and has short slits on the sides, so you can style the shirt as you like, for example knot at the front, tuck into the waistband or wear as usual.
