Eunice asked what Song Joong Ki wore in Descendants of the Sun episodes 1-4. This is what we found so far and we will continuously update this post as we make more finds. (Note: For army uniforms, 99% of the time TV/movie production have costume designers make them so it's safe to say the ones in this drama are customized.)

Song Joong Ki is wearing:

Classic Sweatshirt from Thom Browne

Aloha 3 Bracelet from MZUU

One more request, this time from hola. This part it's the sunglasses from BTS's 'Run' MV. So let's check it out right now ↓

V is wearing a pair of ROUND FOLDING from Ray-Ban.
