GTA Online players seeking to get new clothes should know that the recent update has introduced several Party Shirts. Anybody interested in this new apparel can buy them from any clothing store. It doesn't matter if you visit Binco, Suburban, or Ponsonbys since they all sell the same shirts in this game. As long as the player doesn't go to a specialized store like the LS Car Meet or the Diamond Casino, they should be fine.
You can easily find Binco, Suburban, or Ponsonbys by looking at the world map and searching for a logo that looks like a shirt. Visit whichever store is closest to you. Once inside, search for the tops section and scroll down to Party Shirts, as shown in the following section of this guide.
Here is how GTA Online players can get the new Party Shirts from the recent update

You should see Party Shirts in the 34th spot. There should be a yellow star if you haven't seen all the new content yet. Once you select it, you should see something similar to the following image.

Many of the new Party Shirts cost somewhere in the $25,000 range. Search through each one to find something you might enjoy. After all, personal taste in aesthetics is subjective. Regarding new content, search for anything that says "Part of Los Santos Drug Wars" at the bottom.

GTA Online players can purchase several new Party Shirts from the Los Santos Drug Wars update. The Downtown Cab Co. Revere Collar is old, but it still counts as part of the Los Santos Drug Wars collection. Otherwise, you can buy the other shirts from the latest weekly update.
