Thom Browne TB-101 - Kendrick Lamar - Taylor Swift Bad Blood music video
The sunglasses seem to be the rare Thom Browne TB-101 Original Sunglasses in the colour matte graphite or black iron (thanks to Ivandro for contacting us with this ID). The Thom Browne TB-101 can sometimes be found on eBay, or on Amazon or GranOptic. The same model is also available with a gold and black iron frame,
A similar pair of sunglasses is the Dita Journey (thanks to Jerry for the tip), but the frame is slightly different from the pair worn by Lamar.
