Finn told Luca to dress up, but Luca didn't really have much choice in his closet for himself.
The fashion industry had completely died out ever since the Dawn virus took over the world. Fashion companies were forced to close down their businesses because people no longer cared about the latest trends, and they were more focused on how they were going to survive the disaster.
At this time, there was only one clothing factory in the East Block, and it was owned by the block's management. There were a few retail stores that got clothes from that factory in the four districts of the block, but they also couldn't sell the clothes at a high price because people in this era couldn't make money easily. That was why the retail stores didn't have much stock in their stores, and even the clothing choices were limited. However, people could ignore what they had to wear as long as it covered their bodies, and Luca thought the same.
