This might single-handedly be the worst update beside Dynamic heads. They are going out of their way to ruin everything that the platform is built upon.
No doubt that 3D clothing uploads becoming cheaper has something to do with classic clothing being removed/deprecated.
Publishing 2D clothing on Roblox now requires an active Premium 1000 or 2200 subscription to sell items or keep them on sale.
This means that 2D clothing from inactive creators like 1blox, Tophthetomboy, etc. will soon go off-sale.
